Perturbations of black holes, initially considered in the context of possible observations of
astrophysical effects, have been studied for the past 10 years in string theory, brane-world …

Important properties of a particle, wave or a statistical system depend on the form of a
dispersion relation (DR). Two commonly-discussed dispersion relations are the gapless …

We generalize recent work to construct a map from the conformal Navier Stokes equations
with holographically determined transport coefficients, in d spacetime dimensions, to the set …

We study the poles of the retarded Green functions of a holographic superconductor. The
model shows a second order phase transition where a charged scalar operator condenses …

A bstract Photon spheres are the characteristic of general black holes, thus are a suitable
touchstone for the emergence of gravitational spacetime in the AdS/CFT correspondence …

In this work, we utilize the quasinormal modes (QNMs) of a massless scalar perturbation to
probe the Van der Waals-like small and large black holes (SBH/LBH) phase transition of …

We revisit the problem of calculating the quasinormal modes of spin 0, 1/2, 1, 3/2, 2, and
spin 5/2 fields in the asymptotically flat Schwarzschild black hole spacetime. Our aim is to …

We investigate the scalar, gravitational, and electromagnetic quasinormal mode spectra of
Schwarzschild anti–de Sitter black holes using the numerical continued fraction method. The …

Using gauge/gravity duality techniques, we discuss the sound-channel retarded correlators
of vector and tensor conserved currents in a class of (2+ 1)-dimensional strongly-coupled …

We study the quasinormal mode (QNM) spectrum of an asymptotically AdS black hole with
the Robin boundary condition at infinity. We consider the Schwarzshild-AdS 4 with the flat …
