Now, for the first time, a signal has been measured that is believed to be precisely this phenomenon. Thomas Nilsson, Professor at the Department of Physics at Chalmers University of Technology, has participated in the experiment and tells us more about the discovery. </b></p>​<span style="background-color:initial">Our world is made up of atoms, whose nuclei consist of protons and neutrons. Whether a system made up entirely of neutrons can exist has long eluded the world of physics, and more than half a century has passed since searching for it began. Twenty years ago, scientists found signs of the tetraneutron after an experiment in which neutron-rich beryllium isotopes collided with carbon atoms, but the result had large margins of error and was difficult to interpret.</span><div><br /></div> <div>During a large-scale experiment carried out by a big international research team at the Radioactive Ion Beam Factory at RIKEN in Japan, it has now been possible for the first time to demonstrate what is believed to be an observation of the tetraneutron; four neutrons that are fleetingly connected. The experiment was carried out in 2016, but it has taken until now to analyse the complex measurements, <a href="https://doi.org/10.1038/s41586-022-04827-6">the results of which have been presented in Nature</a>.</div> <div><br /></div> <div style="font-size:16px">Better understanding of the atomic nucleus</div> <div><br /></div> <div><strong><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Thomas%20Nilsson_400x415.jpg" class="chalmersPosition-FloatRight" alt="Thomas Nilsson" style="margin:5px 10px;width:180px;height:189px" />Thomas Nilsson</strong>, Professor of experimental subatomic physics and Head of the Department of <span style="background-color:initial">Physics at Chalmers, is part of the research team. In short, the driving force behind this type of research is the curiosity to better understand the world, he says.</span></div> <div><br /></div> <div>“The tetraneutron can help us understand the microcosm and how the atomic nucleus is built right down to the quark level – the smallest demonstrated building blocks of matter. It would be an extreme system to study and could give us insights into the strong interaction between neutrons and protons in an atomic nucleus, one of the four interaction types found in nature and the most complicated one to study, says Thomas Nilsson.</div> <div><br /></div> <div>“The tetraneutron can also give us insights into the processes that take place in the universe's neutron stars. Large parts of them are made up of neutrons alone, and it is believed that heavy elements are created when neutron stars collide.”</div> <div><br /></div> <div style="font-size:16px">A neutron star in the lab</div> <div><br /></div> <div>Experimental studies of neutron systems are challenging because free neutrons decay within minutes. Therefore, the researchers cannot start from them. To create a system where the neutrons could interact only with each other during the experiment, the researchers used nuclear reactions with atomic nuclei that already have a large excess of neutrons. The researchers overcame the challenge by creating a beam of the isotope helium-8 (with two protons and six neutrons) and firing it at half the speed of light at a target of hydrogen. Thus, a collision was created where sometimes only four neutrons remained. In turn, they formed into a system of four – albeit as fleetingly as for 10<sup>-</sup><sup>22</sup> seconds (0.0000000000000000000001 seconds).</div> <div><br /></div> <div>By measuring the mass and energy of the particles before and after the collision, the tetraneutron could be detected by the energy that was missing in the measurement after the collision.</div> <div><br /></div> <div>“In the past there have been indications of the tetraneutron, but they have not been statistically significant. Now we have received a very clear signal and you can say that we have possibly created a minimal neutron star in the lab”, says Thomas Nilsson.</div> <div><br /></div> <div>Further studies will be required to confirm the result of the experiment. In a few years, the German accelerator facility FAIR, Facility for Antiproton and Ion Research, is expected to be completed. There, the researchers will, among other things, be able to produce matter that is usually only found in space.</div> <div><br /></div> <div>“At FAIR, you will be able to measure all four neutrons separately. Then we will really be able to say whether it is a four-neutron system that we have found”, says Thomas Nilsson.</div> <div><br /></div> <div style="font-size:15px"><strong>More about the scientific article and the research:</strong></div> <div><ul><li>The article <a href="https://doi.org/10.1038/s41586-022-04827-6">“Observation of a correlated free four-neutron system“</a>, M.

This is also the case when laser light is shined onto a mirror. The reflected light field contains information about the mirror’s position. This measurement scheme is for example used in gravitational wave detectors. The information about the mirror’s position can be vastly increased by capturing the light between two mirrors, in so-called cavity optomechanical systems. These systems not only enable measuring the position of the mirror very precisely, but also controlling its motion, even to its quantum mechanical ground state. This has fascinated scientists as it allows exploring the validity of quantum physical laws for larger objects. The next major challenge in this research field is to increase the interaction between light and the motion of the mirror until it is possible to create quantum mechanical states of the mirror directly. </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">The aim of this project is to reach the so-called nonlinear regime of quantum optomechanics in chip-based devices.

If one succeeds with this ambitious goal, one can, for instance, detect individual photons without destroying them and the quantum information that they carry. An important area of application of this ability lies in the field of quantum technology. For example, having access to the nonlinear regime could lead to the development of novel chip-based devices that can detect significantly smaller forces and displacements than what the most advanced technologies allow us to do today.<span> </span> </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><strong>Grant: </strong>SEK 27,000,000 over five years </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><strong>Principal investigator:</strong> Associate Professor <a href="/en/staff/Pages/witlef-wieczorek.aspx">Witlef Wieczorek​</a>, Department of Microtechnology and Nanoscience (MC2)</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><strong>Co-applicants in the project:</strong> Andreas Isacsson and Philippe Tassin (Physics) and Janine Splettstoesser (MC2), and encompasses Chalmers' expertise in experiment, theory, and artificial intelligence. </p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"><strong>Read more: </strong><a href="https://kaw.wallenberg.org/en/research-projects-2022">KAW Research Projects 2022</a></p> <div> </div> <p class="chalmersElement-P"> ​</p>Fri, 14 Oct 2022 09:00:00 +0200https://www.chalmers.se/en/departments/physics/news/Pages/Revealing-the-mysteries-of-the-universe-under-the-skin-of-an-atomic-nucleus.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Revealing-the-mysteries-of-the-universe-under-the-skin-of-an-atomic-nucleus.aspxRevealing the mysteries of the universe under the skin of an atomic nucleus<p><b>​​Massive neutron stars colliding in space are thought to be able to create precious metals such as gold and platinum.

It enables high precision predictions of properties for the isotope* lead-208 and its so-called ‘neutron skin’.</div> <div><br /></div> <div style="font-size:20px">The thickness of the skin matters</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Christian%20Forssen.jpg" class="chalmersPosition-FloatRight" alt="Christian Forssén" style="margin:5px" />It is the 126 neutrons in the atomic nucleus that form an outer envelope, which can be described as a skin. How thick the skin is, is linked to the properties of the strong force. By predicting the thickness of the neutron skin, knowledge can increase about how the strong force works – both in atomic nuclei and in neutron stars.</div> <div><br /></div> <div>&quot;We predict that the neutron skin is surprisingly thin, which can provide new insights into the force between the neutrons. A groundbreaking aspect of our model is that it not only provides predictions, but also has the ability to assess theoretical margins of error. This is crucial for being able to make scientific progress,&quot; says research leader <strong>Christian Forssén</strong>, Professor at the Department of Physics at Chalmers.</div> <div><br /></div> <div style="font-size:20px">Model used for the spread of the coronavirus</div> <div><br /></div> <div>To develop the new computational model, the researchers have combined theories with existing data from experimental studies. The complex calculations have then been combined with a statistical method previously used to simulate the possible spread of the coronavirus.</div> <div><br /></div> <div>With the new model for lead, it is now possible to evaluate different assumptions about the strong force. The model also makes it possible to make predictions for other atomic nuclei, from the lightest to the heaviest.</div> <div>The breakthrough could lead to much more precise models of, for example, neutron stars and increased knowledge of how these are formed.</div> <div><br /></div> <div>&quot;The goal for us is to gain a greater understanding of how the strong force behaves in both neutron stars and atomic nuclei. It takes the research one step closer to understanding how, for example, gold and other elements could be created in neutron stars – and at the end of the day it is about understanding the universe,&quot; says Christian Forssén.</div> <div> </div> <div style="font-size:16px">More about the scientific study</div> <div><ul><li>The scientific article <a href="https://doi.org/10.1038/s41567-022-01715-8">&quot;Ab initio predictions link the neutron skin of 208Pb to nuclear forces&quot;</a> has been published in Nature Physics and is written by Baishan Hu, Weiguang Jiang, Takayuki Miyagi, Zhonghao Sun, Andreas Ekström, Christian Forssén, Gaute Hagen, Jason D.
