Disordered Charged Horizons
Daniel Arean, Sebastian Grieninger, Pau G. Romeu
We construct fully backreacted charged black brane solutions with a spatially disordered chemical potential in asymptotically AdS and AdS, providing holographic duals of st…
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…
Holographic Non-Hermitian Lattices and Junctions and their RG Flows
Daniel Arean, David Garcia-Fariña
We construct and study inhomogeneous non-Hermitian strongly coupled holographic field theories. We consider two models: a lattice where in each site there is some inflow/outflow of…
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…
Pseudospectra of Holographic Quasinormal Modes
Daniel Arean, David Garcia-Fariña, Karl Landsteiner
Quasinormal modes and frequencies are the eigenvectors and eigenvalues of a non-Hermitian differential operator. They hold crucial significance in the physics of black holes. The a…
Pseudo-spontaneous Symmetry Breaking in Hydrodynamics and Holography
Martin Ammon, Daniel Arean, Matteo Baggioli +2
We investigate the low-energy dynamics of systems with pseudo-spontaneously broken symmetry and Goldstone phase relaxation. We construct a hydrodynamic framework which is ab…
