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…

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…

Chiral Magnetic Effect enhancement at lower collision energies
Sebastian Grieninger, Sergio Morales-Tejera, Pau G. Romeu
We extend previous holographic studies of the Chiral Magnetic Effect (CME) by incorporating a time-dependent magnetic field. Various magnetic field profiles proposed in the literat…
