Non-Hermitian Holographic Flows to Little Rip Cosmologies
Daniel Arean, David Garcia-Fariña, Juan F. Pedraza
Spacelike singularities supported by matter satisfying the null energy condition (NEC) are expected to fall within the Belinski--Khalatnikov--Lifshitz (BKL) paradigm. We show that…
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…
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 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…
