Indeed, atomic nuclei bring us closer to study both the stellar explosions in the macrocosmos, where the elements are formed, and the fundamental symmetries of the microcosmos. Having access to a a precise description of the interactions between protons and neutrons would provide a key to new knowledge across 20 orders of magnitude; from neutrinos to neutron stars.<br /></div> <div> </div> <div>In this lecture I will discuss novel methodologies to use experimental information from heavy atomic nuclei in the construction of nuclear interactions from chiral effective field theory. I expect this strategy to create clear scientific advantage and allow me to tackle the following big research questions: To what extent can nuclei be described in effective field theories of quantum chromo dynamics? How do we estimate the uncertainties in theoretical predictions ?</div>https://www.chalmers.se/en/centres/gpc/calendar/Pages/COLL_Matthias_Neubert_190124.aspxhttps://www.chalmers.se/en/centres/gpc/calendar/Pages/COLL_Matthias_Neubert_190124.aspxGeneral Physics Colloquium by Matthias Neubert<p>PJ, lecture hall, Fysikgården 2B, Fysik Origo</p><p>​Title: Probing beyond the Standard Model with Flavor Physics Matthias Neubert, Johannes Gutenberg University Mainz, Germany</p><h4 class="chalmersElement-H4">Abstract:</h4> <div>The persistent flavour anomalies in semileptonic and rare leptonic decays of B mesons are among the most compelling hints of physics beyond the Standard Model (SM). Particular exciting in this context are the hints for violations of lepton-flavour universality. The status of these anomalies will be reviewed and their implications for physics beyond the SM will be discussed.​</div>https://www.chalmers.se/en/departments/physics/calendar/Pages/Lunch_concert_190125.aspxhttps://www.chalmers.se/en/departments/physics/calendar/Pages/Lunch_concert_190125.aspxLunch concert at Physics: Vivi Felice!<p>Physics Centre Personnel room, Origo building, 4th floor</p><p>​Enjoy your Friday lunch accompanied by some live music.​ Talk about and keyboard music by Domenico Scarlatti with Måns Henningson, Physics Dept.

Title: Many candidates new in the zoo: Towards unifying principles in liquid exfoliation of various layered crystals Lecturer: Claudia Backes, Applied Physical Chemistry, Heidelberg University, Germany</p><div><h4 class="chalmersElement-H4">Abstract:</h4> <div><span style="background-color:initial">2D materials are exciting for two reasons: i) layer number dependent properties and ii) the broad palette of accessible layered crystals potentially giving access to any desired function. Ten years ago, it was demonstrated that 2D nanosheets can be obtained from layered crystals via liquid phase exfoliation (LPE) resulting in colloidal dispersions. However, sample polydispersity was a problem until recently. Now, we have arrived at a point where size selection (e.g. liquid cascade centrifugation, LCC) and size measurement protocols are in place, which can be readily applied to the whole nanosheet zoo. By comparing various materials, a model to understand the exfoliation was developed. </span></div></div> <div>With our realisation that both size and thickness result in changes in optical extinction spectra due to edge and confinement effects, it became possible to quantitatively determine the nanosheet dimensions optically. Such metrics have now been developed for ~15 materials. The understanding of the optical spectra is useful to monitor degradation kinetics in various liquids as function of time/temperature. Activation energies can be determined and passivation of defects, e.g. by functionalisation, subsequently studied. Functionalisation in general has the potential to ultimately enable the fabrication of hybrids, vertical and horizontal heterostacks etc. for new functional materials. </div>https://www.chalmers.se/en/departments/physics/calendar/Pages/Licentiatseminarium_Mathias_Hoppe_190201.aspxhttps://www.chalmers.se/en/departments/physics/calendar/Pages/Licentiatseminarium_Mathias_Hoppe_190201.aspxLicentiate seminar: Mathias Hoppe<p>PJ, lecture hall,</p><p>​ T​itle of thesis: Simulation and analysis of radiation from runaway electrons</p><h4 class="chalmersElement-H4">Abstract:</h4> <div><span style="background-color:initial">Runaway electrons constitute one of the primary threats to future </span><span style="background-color:initial">toka</span><span style="background-color:initial">mak</span><span style="background-color:initial"> fusion reactors such as ITER.
