Math Phys/Phys seminar Fyrirlesari: Jens H. Bárðarson, KTH Stockholm Titill: On the chiral anomaly in Weyl semimetals Staðsetning: VR-II 158 Tími:þriðjudagur 4. desember, kl. 13.30 Ágrip: I will give an introduction to the physics of Weyl semimetals focussing on Fermi arcs and chiral anomaly. I will then discuss some transport properties of Weyl semimetals including strongly
Málstofa í stærðfræði Fyrirlesari: Hermann Þórisson, University of Iceland Titill: What is typical? Staðsetning: Naustið (Endurmenntun) Tími: Föstudagur 30. nóvember kl. 11.40 Ágrip: The word “typical” is often used in a loose sense for events in a stationary random process (such as occurrences of heads in repeated coin tosses). This concept can be made precise using so-called Palm
Málstofa í stærðfræði Fyrirlesari: Watse Sybesma, University of Iceland Titill: Black holes and good vibrations Staðsetning: Naustið (Endurmenntun) Tími: Föstudagur 23. Nóvember kl. 11.40 Ágrip: Matter falling into a black hole is a dynamical process that can be described by a complicated wave equation, which has to be disentangled from a system of PDEs. Computing the eigenvalues
Math Phys seminar Fyrirlesari: Aruna Rajagopal, University of Iceland Titill: Shock and Rarefaction Waves in Out of Equilibrium Lifshitz Fluids Staðsetning: VR-II 155 Tími: Fimmtudaginn 22. nóvember 22 kl. 13.30 Ágrip: Motivated by the recent developments and interest in the emergence of a non equilibrium steady state or NESS, for a relativistic fluid, and its possible
Málstofa í stærðfræði Fyrirlesari: Hjalti Þór Ísleifsson, University of Iceland Titill: Veik grannmynstur á Banach rúmum. Staðsetning: Naustið (Endurmenntun) Tími: Föstudagur 16. Nóvember kl. 11.40 Ágrip Við byrjum á að skilgreina veika grannmynstrið á normrúmum og veika* grann- mynstrið á tvírúmum þeirra. Grundavallar eiginleikar þessarra grannmynstra verða kynntir til en sérstök áhersla verður á að skoða þjappleika.
Málstofa í stærðfræði Fyrirlesari: Þórður Jónsson, University of Iceland Titill: The structure of the spatial slices of 3-dimensional causal triangulations Staðsetning: Naustið (Endurmenntun) Tími: Föstudagur 2. Nóvember kl. 11.40 Ágrip: We show that there is a bijection between the spatial slices of 3-dimensional causal triangulations and a class of two-dimensional cell complexes satisfying some simple conditions. The
Math Phys seminar Fyrirlesari: Daniel Areán, IFT Madrid Titill: Breaking translations in AdS/CMT: Holographic Bad Metals Staðsetning: Naustið (Endurmenntun) Tími: Wednesday October 24, 13.30 – 14.30 Ágrip: We present holographic models realizing the pseudo-spontaneous breaking of translations. We study the electrical transport of these solutions finding that they reproduce features characteristic of the bad metallic transport observed
