A Holographic prescription for generalized Schwinger-Keldysh contours
Martin Ammon, Jette Germerodt, Christoph Sieling +1
We provide a holographic prescription to compute real-time thermal correlators with arbitrary operator ordering. In field theory, these correlation functions are captured by a mult…
The entanglement membrane in 2d CFT: reflected entropy, RG flow, and information velocity
Hanzhi Jiang, Márk Mezei, Julio Virrueta
The time evolution of entanglement entropy in generic chaotic many-body systems has an effective description in terms of a minimal membrane, characterised by a tension function. Fo…
Anomalous hydrodynamics effective actions from holography
Mukund Rangamani, Julio Virrueta, Shuyan Zhou
We derive an effective action for charged plasmas with an anomalous (abelian) global current charge current using holography. The holographic description is captured by the dynamic…
Holographic thermal correlators: A tale of Fuchsian ODEs and integration contours
R. Loganayagam, Mukund Rangamani, Julio Virrueta
We analyze real-time thermal correlation functions of conserved currents in holographic field theories using the grSK geometry, which provides a contour prescription for their eval…
Holographic open quantum systems: Toy models and analytic properties of thermal correlators
R. Loganayagam, Mukund Rangamani, Julio Virrueta
We present a unified picture of open quantum systems, the theory of a system probing a noisy thermal environment, distilling lessons learnt from previous holographic analyses. Our…
An effective description of charge diffusion and energy transport in a charged plasma from holography
Temple He, R. Loganayagam, Mukund Rangamani +1
We discuss the physics of sound propagation and charge diffusion in a plasma with non-vanishing charge density. Our analysis culminates the program initiated in arXiv:2108.03244 to…
The timbre of Hawking gravitons: an effective description of energy transport from holography
Temple He, R. Loganayagam, Mukund Rangamani +2
Planar black holes in AdS, which are holographically dual to compressible relativistic fluids, have a long-lived phonon mode that captures the physics of attenuated sound propagati…
An effective description of momentum diffusion in a charged plasma from holography
Temple He, R. Loganayagam, Mukund Rangamani +1
We discuss the physics of momentum diffusion in a charged plasma. Following the holographic strategy outlined in arXiv:2012.03999 we construct an open effective field theory for th…
Exploring the Membrane Theory of Entanglement Dynamics
Márk Mezei, Julio Virrueta
Recently an effective membrane theory valid in a "hydrodynamic limit" was proposed to describe entanglement dynamics of chaotic systems based on results in random quantum circuits…
The Quantum Null Energy Condition and Entanglement Entropy in Quenches
Márk Mezei, Julio Virrueta
The Quantum Null Energy Condition (QNEC) relates energy to the second variation of entropy in relativistic quantum field theory. We use the QNEC inequality to bound entanglement en…
Superconformal Models for Graphene and Boundary Central Charges
Christopher P. Herzog, Kuo-Wei Huang, Itamar Shamir +1
In the context of boundary conformal field theory, we investigate whether the boundary trace anomaly can depend on marginal directions in the presence of supersymmetry. Recently, i…
Holographic Entanglement Entropy in Time Dependent Gauss-Bonnet Gravity
Elena Caceres, Manuel Sanchez, Julio Virrueta
We study holographic entanglement entropy in Gauss-Bonnet gravity following a global quench. It is known that in dynamical scenarios the entanglement entropy probe penetrates the a…
CP violating phase from charged-lepton mixing
J. Alberto Acosta, Alfredo Aranda, Julio Virrueta
A model independent analysis of the leptonic Dirac CP-violating phase (δ) is presented. The analysis uses the experimentally determined values of the mixing angles in the lepton mi…
