Events: Space, Earth and Environment, Rymd- och geovetenskap, Energi och miljö events at Chalmers University of TechnologyFri, 21 Sep 2018 08:45:20 +0200 will receive the Nobel Prize in Physics 2018?<p>Kollektorn, lecture room,</p><p>​Let&#39;s find out together! Forum för tekniska fysiker (forum for engineering physicists) invites all of you to a sparkling new presentation of the Nobel Prize in Physics.</p><div>Together we will follow the live broadcast of the Royal Swedish Academy of Sciences announcement of the Nobel Prize in Physics. This will take place no earlier than 11.45. After the Academy's decision we will learn a bit more about the laureate/laureates and hopefully, we can listen to a live interview in connection with the press conference.</div> <br /><div>Welcome to attend the event!</div> <div><br /></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />To the homepage of Forum för tekniska fysiker. </a> <br /></div> <br /> Kierdorf, Max Planck Institut für Radio Astronomie<p>Onsala rymdobservatorium, space observatory, Seminarierummet</p><p>​Probing the Magnetized Disk - Halo Transition Region in M51 via Wideband Polarimetry</p>​Abstract:<div><p class="MsoPlainText">An excellent laboratory for studying  well ordered magnetic fields is the grand design face-on spiral galaxy M51. Due to wavelength-dependent Faraday depolarization, polarized emission at different radio frequencies gives a picture of the galaxy at different depths: previous observations at L-band (1-2GHz) probes the halo region while at C-band (4-8GHz) the polarized emission comes from the disk region of M51. In this talk, I will present new observations of M51 with the Very Large Array at S-band (2-4GHz), where currently no polarization data exists, to shed new light on the transition region between disk and halo. The wide frequency coverage and high spatial resolution of about 7 arcsec allow us to probe the disk-halo transition region to get detailed information on the magnetic field structure in the plane of the sky and on the vertical magnetic field component in this unknown layer.</p> <p class="MsoPlainText">Previous models applied to the polarized emission shows different behavior for different magnetic field configurations in the disk and halo. I will show our observational results of the transition layer, which is critical for our understanding on the origin of large-scale halo fields and how they are connected to the underlying galactic disk.</p></div> Sustainability Day 2018<p>Campus Johanneberg, mostly at Chalmers conference centre, Student Union Building</p><p>​Chalmers Sustainability Day is back - Tuesday 23 October 2018.

Recent focus on FeSe has been centered on the connection between nematicity and superconductivity, and the possibility of enhancing Tc in monolayers on STO, or by pressure. In this talk, I will give and overview of recent developments and focus on recent scanning tunneling experiments mapping out the detailed spectroscopic features of FeSe by the group of J. C. Seamus Davis at Cornell University. I will explain the recent evidence for orbital selective superconducting pairing, and the direct detection of orbital selective quasiparticles by quasi-particle interference. This highlights the correlated nature of FeSe, more specifically its Hund’s metal nature with coexisting orbital-dependent coherent and incoherent low-energy states. I then proceed to discuss the theoretical modelling of these phenomena and the implications for our understanding of the origin of superconductivity in FeSe in particular, and in the iron-based superconductors in general.</span></div> ​ Physics Colloquium<p></p><p>Colloquium by the Nobel Prize Laureate Takaaki Kajita​.</p>
