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…

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…
