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 …
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 …
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 …
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 …
Math Phys seminar Fyrirlesari: Tobias Zingg, Nordita Titill: plasmons and physical density-density response from holography Staðsetning: Aðalbygging A-069 Tími: Thursday October 4, at 1.20 -2.20 pm Ágrip: The holographic correspondence can be extended to identify plasmonic excitations in strongly correlated systems. These modes have relevance in the growing field of plasmonics, and play also a crucial role …
