We study the hydrodynamic excitations of backreacted holographic superfluids by computing the full set of quasinormal modes (QNMs) at finite momentum and matching them to the existing hydrodynamic theory of superfluids. Additionally, we analyze the b

Hydrodynamics provides a universal description of interacting quantum field theories at sufficiently long times and wavelengths, but breaks down at scales dependent on microscopic details of the theory. In the vicinity of a quantum critical point, it

Pseudospectra of quasinormal modes and holography

Autor: Daniel Areán, David Garcia-Fariña, Karl Landsteiner

Publikováno v: Frontiers in Physics, Vol 12 (2024)

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 asymptotically anti-de Sitter space. One of the cornerstones of this dua

Pseudospectra of holographic quasinormal modes

Autor: Daniel Areán, David García Fariña, Karl Landsteiner

Publikováno v: Journal of High Energy Physics, Vol 2023, Iss 12, Pp 1-60 (2023)

Abstract 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 analysis of quasinormal modes of black holes in asymptotically

We study a holographic model where translations are both spontaneously and explicitly broken, leading to the presence of (pseudo)-phonons in the spectrum. The weak explicit breaking is due to two independent mechanisms: a small source for the condens
