[:is]Math colloquium Fyrirlesari: Björn Birnir, Center for Complex and Nonlinear Science at the University of California at Santa Barbara (UCSB) Titill: When can we expect the Greenland glacier to melt? Staðsetning: VR-II,V-258Tími: Þriðjudag 27.ágúst kl. 11:00 Ágrip: It was suggested by Rose (2005) that because of the migratory and responsive nature of the capelin, a […]
[:is] Math Phys seminar Fyrirlesari: Hólmfríður Sigríðar Hannesdóttir , Harvard University Titill: Infrared Finite S-matrix elements and Cross Sections Staðsetning: A-050Tími: Þriðjudag 27.ágúst kl. 14:00 Ágrip: Quantum field theory (QFT) works remarkably well for making theoretical predictions in collider scattering experiments. One of the fundamental objects in these calculations, the scattering matrix (S-matrix), is inspired

[:is] PhD midway evaluation Fyrirlesari: Juan Fernando Angel Ramelli, HÍ Titill: Entanglement entropy of the quantum Lifshitz model Staðsetning: A-050Tími: Þriðjudag 27.ágúst kl. 09:00 Ágrip: The quantum Lifshitz model (QLM) is a toy model used for studying scale invariant systems in which time and space scale on different footing. This type of behavior occurs, for example,

[:is]Math Phys seminar Fyrirlesari: Mohab Abou Zeid, Imperial College London Titill: T-duality in (2,1) superspace and SKT geometry Staðsetning: VR-II, V-156Tími: Föstudag 23.ágúst kl. 14:00 Ágrip: I will explain our recent derivation of the T-duality transformation rules for two-dimensional (2,1) supersymmetric sigma-models in (2,1) superspace. To this end I will first review the gauging of sigma-models in
[:is]Math Phys seminar Fyrirlesari: Ro Jefferson, Albert Einstein Institute Potsdam Titill: Black hole interiors and modular inclusions Staðsetning: VR-II, V-156Tími: Fimmtudag 22.ágúst kl. 14:00 Ágrip: We show how the traversable wormhole induced by a double-trace deformation of the thermofield double state can be understood as a modular inclusion of the algebras of exterior operators. The effect of
[:is]Math Phys seminar Fyrirlesari: Arnbjorg Soffia Arnadottir,University of Waterloo Titill: Continuous Quantum Walks Staðsetning: VR-II, V-158 Tími: Fimmtudag 22.ágúst kl. 11:00 Ágrip: Continuous quantum walks arise naturally as quantum analogues of continuous random walks, but in contrast to their classical counterparts, they exhibit some curious and counter-intuitive properties. I will give an introductory talk on continuous quantum walks

[:is]Math Phys seminar Fyrirlesari: Jorge Laraña Aragon,University of Stockholm Titill: Quenched coupling, effective thermalization and evanescence in the free $O(N)$ vector model Staðsetning: VR-II, V-156Tími: Fimmtudag 15.ágúst kl. 14:00 Ágrip: In this project we study two coupled free $O(N)$ vector models implementing the coupling via a quench of mixing. Since the theory is integrable pure thermalization

[:is]Málstofa í stærðfræði Fyrirlesari: Finnur Lárusson, Adelaide University Titill: Chaotic holomorphic automorphisms of Stein manifolds with the volume density property Staðsetning: VR-II, V-158Tími: þriðjudagur 9. júlí kl. 11.00 Ágrip: I will report on joint work with Leandro Arosio. Let $X$ be a Stein manifold of dimension $n\geq 2$ satisfying the volume density property with respect to an exact
[:is]Math Phys seminar Fyrirlesari: Christiana Pantelidou, Durham University Titill: Incoherent hydrodynamics and density waves Staðsetning: VR-II, V-258Tími: mánudagur 24. júní kl. 14.00 Ágrip: I will consider thermal phases of holographic lattices at finite chemical potential in which a continuous internal bulk symmetry can be spontaneously broken. In the normal phase, translational symmetry is explicitly broken
