Anomalous Transport and Explicit Symmetry Breaking in Holography
Ashis Tamang, Nishal Rai, Karl Landsteiner +1
We consider a holographic Einstein-Maxwell model in five dimensions with pure gauge and mixed gauge-gravitational Chern-Simons terms to study anomaly-induced transport in the prese…
Pseudospectra of holographic diffusion: gauge fields breaking free from the master scalar
David Garcia-Fariña, Karl Landsteiner, Pau G. Romeu +1
We study pseudospectra of quasinormal frequencies and complex linear momenta of a U(1) gauge field in a Schwarzschild black branes in Anti-de Sitter. We present a novel approach fo…
Anomaly induced transport from symmetry breaking in holography
Ashis Tamang, Nishal Rai, Karl Landsteiner +1
We study the transport properties of relativistic fluids induced by quantum anomalies in presence of explicit symmetry breaking. To this end we consider a holographic Einstein-Maxw…
Strongly Coupled PT-Symmetric Models in Holography
Daniel Arean, David Garcia-Fariña, Karl Landsteiner
Non-Hermitian quantum field theories are a promising tool to study open quantum systems. These theories preserve unitarity if PT-symmetry is respected, and in that case an equivale…
Hydrodynamic Modes of Holographic Weyl Semimetals
Nishal Rai, Karl Landsteiner
We study the quasinormal modes of a holographic model of a Weyl semimetal. The model features quantum phase transition between a topological phase and a trivial phase. We put parti…
Pseudospectra of complex momentum modes
David Garcia-Fariña, Karl Landsteiner, Pau G. Romeu +1
We initiate the study of stability and pseudospectra of complex momentum modes of asymptotically anti-de Sitter black holes. Similar to quasinormal modes, these can be defined as t…
Pseudospectra of Quasinormal Modes and Holography
Daniel Arean, David Garcia-Fariña, Karl Landsteiner
The holographic duality (also known as AdS/CFT correspondence or gauge/gravity duality) postulates that strongly coupled quantum field theories can be described in a dual way in as…
Holographic -functions and Boomerang RG Flows
Elena Cáceres, Rodrigo Castillo Vásquez, Karl Landsteiner +1
We use the radial null energy condition to construct a monotonic -function for a certain type of non-relativistic holographic RG flows. We test our -function in three differe…
