Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters. ​​​​​</b></p><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/IlliaThiele_190312_01_beskuren_webb.jpg" alt="" style="margin:5px;width:150px;height:224px" /><span style="background-color:initial"><div>“This source of radiation lets us look at reality through a new angle – it is like twisting a mirror and discovering something completely different,” says Illia Thiele, a theoretical physicist at Chalmers University of Technology. <br /></div> <div> </div> <div>Together with Dr Evangelos Siminos at the University of Gothenburg, and Tünde Fülöp, Professor of Physics at Chalmers, Illia Thiele now presents a theoretical method for creating the fastest possible single wave motion.

Since it offers an ultra-fast switching of light matter interactions, it can be useful in material science, or sensor related research, for example. Moreover, it can be used as a driver for other types of radiation, and to push the limits of how short a light pulse could be. <br /></div> <div> </div> <div>“An ultra-intense pulse is like a great tsunami of light. ​The wave can pull an electron out of an atom, accelerating it to almost the speed of light, creating exotic quantum states. This is the fastest and strongest switch possible, and it paves the way for advances in fundamental research,” says Dr Illia Thiele. <br /></div> <div> </div> <div><span><span style="background-color:initial"><img src="/en/departments/physics/news/Documents/siminos_large.jpg_webb_300x450.jpg" alt="siminos_large.jpg_webb_300x450.jpg" class="chalmersPosition-FloatRight" style="margin:5px;width:150px;height:225px" /></span></span>The new pulses can be used to probe and control matter in unique ways.

These so-called sub-cycle pulses can be used to probe and control matter in unique ways. Conventional methods can only produce sub-cycle pulses of limited field strength: above a certain threshold the amplifying medium would be ionized by the intense fields. The researchers propose to use an electron beam in a plasma, which is not subject to a damage threshold, as an amplifying medium for a seed electromagnetic pulse. To ensure that energy is transferred from the electron beam to the pulse in such a way that a sub-cycle pulse is produced, the beam needs to be introduced at an appropriate phase of the oscillation of the electromagnetic field. This can be achieved by using a mirror to reflect the seed pulse while the electron beam is being injected. This scenario leads to significant amplification of the seed pulse and the formation of an intense, isolated, sub-cycle pulse. Readily available terahertz seed pulses and electron bunches from laser-plasma accelerators could generate mid-infrared sub-cycle pulses with millijoule-level energies, which are highly desirable as probes of matter but not possible to produce with conventional sources.</div> <div><br /> </div> <h4 class="chalmersElement-H4">For more information: </h4> <div><a href="http://www.chalmers.se/en/Staff/Pages/Illia-Thiele.aspx">Illia Thiele</a>, Postdoctoral researcher, Department of Physics, Chalmers University of Technology, +46 76 607 82 79,<a href="mailto:illia.thiele@chalmers.se"> illia.thiele@chalmers.se</a><br /></div> <div> </div> <div><span style="background-color:initial"><a href="/en/staff/Pages/Tünde-Fülöp.aspx">Tünde Fülöp,​</a> Professor, Department of Physics, Chalmers University of Technology, +46 72 986 74 40, </span><a href="mailto:tunde.fulop@chalmers.se">tunde.fulop@chalmers.se</a></div> <div><br /><a href="https://www.physics.gu.se/english/about-the-department/staff/?languageId=100001&amp;disableRedirect=true&amp;returnUrl=http://www.physics.gu.se/om-institutionen/personal/?languageId%3D100000%26userId%3Dxsimev&amp;userId=xsimev">Evangelos Siminos</a>, Assistant Professor, Department of Physics, University of Gothenburg</div></span><div><span style="background-color:initial">+46 31 786 9161, <a href="mailto:evangelos.siminos@physics.gu.se">evangelos.siminos@physics.gu.se</a></span></div>Tue, 19 Mar 2019 07:00:00 +0100https://www.chalmers.se/en/departments/physics/news/Pages/Awarded-for-new-foetal-monitoring-method.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Awarded-for-new-foetal-monitoring-method.aspxPhysics students awarded for a promising foetal monitoring method<p><b>​Two master&#39;s students at Chalmers have developed a method for distinguishing a foetus&#39;s heartbeat from the mother’s. It is based on analysing electrical signals that are present naturally in the skin of the mother. These are picked up by electrodes. The method is potentially more reliable and easier to use than current foetal monitoring using a CTG device. The students have been awarded the Bert-Inge Hogsved Prize for Best Entrepreneurship by the Forum for Engineering Physicists at Chalmers. ​</b></p><div><span style="background-color:initial;display:none"></span><img src="/SiteCollectionImages/Institutioner/F/350x305/hogsvedspris_albinodavid_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="background-color:initial" /><span style="background-color:initial">“Cardiotocography, or CTG, is a well-established monitoring method in maternity care. However, it is not always reliable. There is a risk that signals are picked up from the mother's heart rather than the foetus’s, which can have serious consequences. Our way of measuring is potentially more precise, thanks to the advanced electrodes that are now available. We can measure and, using our specially developed analysis, distinguish the foetus’s heartbeat, which can be hundreds of times weaker than the mother’s at the end of pregnancy,” says Albin Annér, one of the prizewinners.        </span></div> <div> </div> <div>The electrodes measure electrical fields in the skin. Unlike with a CTG device, however, they need not be fixed directly onto the skin. The mother does not have to be closely connected to a device, giving her greater freedom of movement. The method is also completely harmless because no current flows between the mother and the electrodes. </div> <div> </div> <div>“Their method is very promising. It could reduce the uncertainties around foetal monitoring and make maternity care safer and simpler in Sweden and internationally,” says Peter Apell, Professor of Living State Physics at Chalmers and the students' co-supervisor with Senior Lecturer Lars Hellberg. </div> <div> </div> <div>The two students are developing the concept as part of the Master's programme in Applied Physics at Chalmers. They are now working on developing a solution suitable for use in a clinical study.</div> <div> </div> <div>“The goal is for our method to replace CTG devices in the long term. The equipment will be lighter, considerably cheaper and smaller, which means it will be more widely available and easily portable. It will be able to be used not only in hospitals but also out in the field, for example in countries with poor access to established healthcare services,” says David Kastö, fellow prizewinner and student with Albin Annér.</div> <div> </div> <div>The prize was established in 2011 by Bert-Inge Hogsved, founder and CEO of the Hogia Group and himself an engineering physicist.

In our field, the main focus is often on the design of a specific type of artificial metamaterials that control light to a high precision by making use of small engineered structures. Our aim was not to develop specific material designs, but to more generally explore what are the physical restrictions on possible applications with metamaterials, hence the title of my thesis “Exploring metamaterial horizons”.</div> <div>A second reason why I think that my thesis stood out is because of how I have visualized and communicated the research in the form of a monograph. I did enjoy the process, because it allowed putting things into context and visualizing the research in a way that is different from the research papers.”</div> <h5 class="chalmersElement-H5">What was the hardest part of the work?</h5> <div>“The coolest and hardest question we were trying to answer is whether metamaterials can behave as artificial black hole analogues. Real black holes are massive objects that deform space and time in an extreme way, for example, time slows down close to the event horizon of a black hole from which nothing can escape, not even light. I really struggled to find how photons behave near this singularity. It took several approximations, some clever analytics, quite a lot of numerics, and a year and a half of dedication, to find out exactly how metamaterials change the notion of space and time.”</div> <h5 class="chalmersElement-H5">… and the best part? </h5> <div>“Professor Uri Alon has a TED talk that nicely captures what I think is the best part of doing a PhD. He explains that doing science is similar to making a journey, starting from a known point A and planning to go to point B. Instead, one ends up getting stuck in a “cloud” of challenges, uncertainties, and maybe even inconsistencies, before emerging from this cloud to point C that is quite different from B. The last year of the thesis was the best part, when finishing up and realizing how things have worked out.”</div> <h5 class="chalmersElement-H5">What piece of advice could you give to future doctoral students?</h5> <div>“Two things have been crucial for me: Interacting with my supervisors and colleagues (try to find a group with nice atmosphere and a sense of sharing) and having chosen a scientific discipline that matches with my research preferences, in my case a young scientific discipline with plenty of opportunities for new methods and ideas.

They both did a great job and their theses are somewhat complementary - one theory, one experiment. However, both are related to light interacting with subwavelength objects, for photonics and material science applications, respectively. Sophie's thesis is exceptionally well written, there is a coherent flow of information throughout the whole work. Moreover, the thesis is very detailed, but at the same time very pedagogical, such that a person outside of the metamaterial field could follow and understand both basic and advanced concepts. Ferry's thesis has a fantastic introduction and motivation part. Also, here there was a great pedagogical and coherence aspect. Ferry is a great writer! Moreover, Ferry's work has generated a considerable cumulative impact due to the substantial amount of high-profile peer-reviewed publications on which the thesis is based (and also the work that was not included).  Altogether, this made us to choose Sophie and Ferry for the best PhD thesis award this time. The prize committee sincerely congratulates Sophie and her supervisor Philippe Tassin, as well as Ferry and his supervisor Christoph Langhammer with this achievement and wishes them success in the future.”</div> <div> </div> <div><a href="/insidan/sites/ap/forskarutbildning/best-thesis-award"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /> See the list of previous winners, check out their theses and see detailed criteria for the award.​</a></div> <div><br /> </div> <div>Text: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se​</a></div> <div>Photo of Ferry Nugroho: Helén Rosenfeldt</div> <div>Photo of Sophie Viaene (at top): Mia Halleröd Palmgren</div> ​​​Wed, 13 Feb 2019 00:00:00 +0100https://www.chalmers.se/en/departments/physics/news/Pages/Investigating-cell-stress-for-better-health-–-and-better-beer.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Investigating-cell-stress-for-better-health-%E2%80%93-and-better-beer.aspxInvestigating cell stress for better health – and better beer<p><b>​Human beings are not the only ones who suffer from stress – even microorganisms can be affected.

They both identified and monitored the change of compounds within the yeast cells, one of which was a sugar, glycerol. Furthermore, they were able to measure the exact rate and amount of glycerol produced by different cells under various stress conditions.

Now, researchers from Chalmers University of Technology, Sweden, present a totally new way to clean contaminated water, through an electrochemical process. The results are published in the scientific journal Nature Communications. ​​​</b></p><div><span style="background-color:initial">“Our results have really exceeded the expectations we had when we started with the technique,” says the research leader Björn Wickman, from Chalmers’ Department of Physics. “Our new method makes it possible to reduce the mercury content in a liquid by more than 99%. This can bring the water well within the margins for safe human consumption.” </span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div>According to the World Health Organisation (WHO), mercury is one the most harmful substances for human health. It can influence the nervous system, the development of the brain, and more. It is particularly harmful for children and can also be transmitted from a mother to a child during pregnancy. Furthermore, mercury spreads very easily through nature, and can enter the food chain. Freshwater fish, for example, often contain high levels of mercury. </div> <div><br /></div> <div>In the last two years, Björn Wickman and Cristian Tunsu, researcher at the Department of Chemistry and Chemical Engineering at Chalmers, have studied an electrochemical process for cleaning mercury from water. Their method works via extracting the heavy metal ions from water by encouraging them to form an alloy with another metal. </div> <div><br /></div> <div>“Today, removing low, yet harmful, levels of mercury from large amounts of water is a major challenge. Industries need better methods to reduce the risk of mercury being released in nature,” says Björn Wickman. </div> <div><br /></div> <img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Vattenrening_labbsetup1_webb.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;background-color:initial" /><div>Their new method involves a metal plate – an electrode – that binds specific heavy metals to it. The electrode is made of the noble metal platinum, and through an electrochemical process it draws the toxic mercury out of the water to form an alloy of the two. In this way, the water is cleaned of the mercury contamination. The alloy formed by the two metals is very stable, so there is no risk of the mercury re-entering the water. </div> <div><br /></div> <div>“An alloy of this type has been made before, but with a totally different purpose in mind. This is the first time the technique with electrochemical alloying has been used for decontamination purposes,” says Cristian Tunsu.</div> <div><br /></div> <div>One strength of the new cleaning technique is that the electrode has a very high capacity. Each platinum atom can bond with four mercury atoms. Furthermore, the mercury atoms do not only bond on the surface, but also penetrate deeper into the material, creating thick layers. This means the electrode can be used for a long time. After use, it can be emptied in a controlled way. Thereby, the electrode can be recycled, and the mercury disposed of in a safe way. A further positive for this process is that it is very energy efficient.</div> <div><br /></div> <div>“Another great thing with our technique is that it is very selective. Even though there may be many different types of substance in the water, it just removes the mercury.

According to the WHO, mercury is one of the most dangerous substances for human health, influencing our nervous system, brain development and more. The substance is especially dangerous for children and unborn babies. </div> <div>Today there are strict regulations concerning the management of toxic heavy metals to hinder their spread in nature. But there are many places worldwide which are already contaminated, and they can be transported in rain or in the air. This results in certain environments where heavy metals can become abundant, for example fish in freshwater sources. In industries where heavy metals are used, there is a need for better methods of recycling, cleaning and decontamination of the affected water. <span style="background-color:initial">​</span></div></div> <div><h3 class="chalmersElement-H3" style="font-family:&quot;open sans&quot;, sans-serif">For more information</h3> <div><span style="font-weight:700"><a href="/en/Staff/Pages/Björn-Wickman.aspx">Björn Wickman​</a></span>, Assistant Professor, Department of Physics, Chalmers University of Technology, +46 31 772 51 79, <a href="mailto:bjorn.wickman@chalmers.se">bjorn.wickman@chalmers.se​</a></div> <div><span style="font-weight:700"><a href="/en/staff/Pages/tunsu.aspx">Cristian Tunsu</a></span>,  Post Doc, Department of Chemistry and Chemical Engineering​, <span style="background-color:initial">Chalmers University of Technology, +46 </span><span style="background-color:initial">31 772 29 45, <a href="mailto:tunsu@chalmers.se">tunsu@chalmers.se</a></span></div></div> <div><div><div><span style="background-color:initial"></span></div></div></div>Wed, 21 Nov 2018 07:00:00 +0100https://www.chalmers.se/en/departments/physics/news/Pages/How-gold-can-melt-at-room-temperature-.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/How-gold-can-melt-at-room-temperature-.aspxHow to melt gold at room temperature<p><b>​When the tension rises, unexpected things can happen – not least when it comes to gold atoms. Researchers from, among others, Chalmers University of Technology, have now managed, for the first time, to make the surface of a gold object melt at room temperature.​</b></p><div><div><div>​<span style="background-color:initial">Ludvig de Knoop, from Chalmers’ Department of Physics, placed a small piece of gold in an electron microscope. Observing it at the highest level of magnification and increasing the electric field step-by-step to extremely high levels, he was interested to see how it influenced the gold atoms.</span></div> <div>It was when he studied the atoms in the recordings from the microscope, that he saw something exciting. The surface layers of gold had actually melted – at room temperature.</div> <div><br /></div> <div>&quot;I was really stunned by the discovery. This is an extraordinary phenomenon, and it gives us new, foundational knowledge of gold,” says Ludvig de Knoop.</div> <div><br /></div> <div>What happened was that the gold atoms became excited. Under the influence of the electric field, they suddenly lost their ordered structure and released almost all their connections to each other.</div> <div>Upon further experimentation, the researchers discovered that it was also possible to switch between a solid and a molten structure.</div> <div><br /></div> <div>The discovery of how gold atoms can lose their structure in this way is not just spectacular, but also groundbreaking scientifically. Together with the theoretician Mikael Juhani Kuisma, from the University of Jyväskylä in Finland, Ludvig de Knoop and colleagues have opened up new avenues in materials science. The results are now published in the journal Physical Review Materials. </div> <div><br /></div> <div>Thanks to theoretical calculations, the researchers are able to suggest why gold can melt at room temperature, which has to do with the formation of defects in the surface layers. <br /><br />Possibly, the surface melting can also be seen as a so-called low-dimensional phase transition. In that case, the discovery is connected to the research field of topology, where pioneers David Thouless, Duncan Haldane and Michael Kosterlitz received the Nobel Prize in Physics 2016. With Mikael Juhani Kuisma in the lead, the researchers are now looking into that possibility. In any case, the ability to melt surface layers of gold in this manner enables various novel practical applications in the future.<br /><span style="background-color:initial"></span></div> <div><br /></div> <div>&quot;Because we can control and change the properties of the surface atom layers, it opens doors for different kinds of applications. For example, the technology could be used in different types of sensors, catalysts and transistors. There could also be opportunities for new concepts for contactless components,&quot; says Eva Olsson, Professor at the Department of Physics at Chalmers.</div> <div><br /></div> <div>But for now, for those who want to melt gold without an electron microscope, a trip to the goldsmith is still in order.</div></div> <div><br /></div> <div><span style="background-color:initial">Text: </span><span style="background-color:initial"> Joshua Worth,</span><a href="mailto:%20joshua.worth@chalmers.se"> joshua.worth@chalmers.se  </a>and <span style="background-color:initial">M</span><span style="background-color:initial">ia </span><span style="background-color:initial">Hall</span><span style="background-color:initial">eröd</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"> Palmgren, </span><span style="background-color:initial"><a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se </a></span><span style="background-color:initial"> </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="color:rgb(33, 33, 33);font-family:&quot;open sans&quot;, sans-serif;font-size:24px;background-color:initial">About the scientific article</span><br /></div> <div><div><span style="background-color:initial">The article </span><a href="https://journals.aps.org/prmaterials/abstract/10.1103/PhysRevMaterials.2.085006">“Electric-field-controlled reversible order-disorder switching of a metal tip surface </a><span style="background-color:initial">” has been published in the journal Physical Review Materials.

He will tell the story about the fascinating journey which led to a groundbreaking underground discovery - and to the Nobel Prize in Physics 2015. ​</b></p><div><span style="background-color:initial"><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/F/350x305/1_Takaaki_Kajita_350x305.jpg" alt="" style="margin:5px;width:320px;height:281px" />What he and Arthur B. McDonald had discovered was oscillations of elusive particles called neutrinos. In the Japanese underground observatory Kamiokande the research group led by Kajita could register the oscillations which showed that the particles, assumed to be massless, actually have mass. The discovery has had profound implications on for example stellar structure and cosmology. <br /></span><br /></div> <div>“Neutrinos are extremely fascinating particles, the second most common (after photons) in the Universe but so elusive that we have a hard time noticing their presence. They are potentially the key to understand some of the deepest questions that still remain unsolved,” says Professor Thomas Nilsson, experimental physicist and Head of the Department of Physics at Chalmers. <br /><br /></div> <div>Neutrinos were created at the birth of the Universe. Today they are created in nuclear processes – in the Cosmos, in our laboratories and in nuclear reactors.<br /><br /></div> <div>“When I joined Kamiokande, underground experiments were just a very small sub-field of particle physics experiments. At present, after more than 30 years, these underground experiments have become some of the most promising, powerful, versatile, and efficient ways to explore both particle physics and the Universe itself. This research underground continues to stimulate my interest. I look forward to what new discoveries the future will hold,” writes Professor Takaaki Kajita in The Nobel Prizes 2015, published on behalf of The Nobel Foundation. <br /><br /></div> <div>At Chalmers, many researchers are looking forward to Professor Kajita’s visit, especially physicists within astro, particle and subatomic physics. <br /><br /></div> <div> “I’m very glad for this event for several reasons. I studied particle physics as a student, but ended up as a reactor physicist, which is a completely different area. Nevertheless, both the existence of neutrinos, as well as two out of the three possible neutrino oscillations were proven by using neutrinos from nuclear reactors,” says Professor Imre Pázsit at the Department of Physics at Chalmers.<br /><br /></div> <div>Due to this fact, and to his extensive collaboration with Japanese physicists, Pázsit got into contact with the neutrino research quite some time ago. He met Professor Kajita in Stockholm in connection to the Nobel ceremony and at the Nobel Dialogue Dinner in Tokyo last year they met again.  <br /><br /></div> <div>“There I understood his interest to visit Sweden again, which of course helped to invite him to Chalmers. I look forward to his lecture and I hope that many will take the opportunity to listen to a fascinating talk,” says Professor Pázsit.</div> <div>Imre Pázsit has collaborated with Japanese researchers for more than 25 years.
