[: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: 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]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

[:is]Math Phys Seminar Fyrirlesari: Bo Sundborg, Stockholm University Staðsetning: Tg 227 („smart room“ Tæknigarður)Tími: Þriðjudaginn 30. apríl, kl. 14:00 Titill: Field theory compositeness, holographic gravity and higher spins Ágrip: I would like to discuss the idea that composite operators in field theory are key ingredients in holograms of bulk gravitational physics. In practice, this is

[:is]Math Phys Seminar Titill: Holographic Complexity of Two-Dimensional Black Holes Fyrirlesari: Lukas Schneiderbauer, HÍ Staðsetning: VR-II 158Tími: Mánudaginn 29. apríl, kl. 10:00 Ágrip: Interest in holographic complexity arose when it was proposed as the dual quantity of the complexity of a quantum state in the context of AdS/CFT. However, it was realized that this quantity
