Exact Gravity Dual of a Gapless Superconductor
George Koutsoumbas, Eleftherios Papantonopoulos, George Siopsis
A model of an exact gravity dual of a gapless superconductor is presented in which the condensate is provided by a charged scalar field coupled to a bulk black hole of hyperbolic h…
Discontinuities in Scalar Perturbations of Topological Black Holes
George Koutsoumbas, Eleftherios Papantonopoulos, George Siopsis
We study the perturbative behaviour of topological black holes. We calculate both analytically and numerically the quasi-normal modes of scalar perturbations. In the case of small…
Graviton localization and Newton's law for brane models with a non-minimally coupled bulk scalar field
K. Farakos, G. Koutsoumbas, P. Pasipoularides
Brane world models with a non-minimally coupled bulk scalar field have been studied recently. In this paper we consider metric fluctuations around an arbitrary gravity-scalar backg…
Quasi-normal Modes of Electromagnetic Perturbations of Four-Dimensional Topological Black Holes with Scalar Hair
George Koutsoumbas, Suphot Musiri, Eleftherios Papantonopoulos +1
We study the perturbative behaviour of topological black holes with scalar hair. We calculate both analytically and numerically the quasi-normal modes of the electromagnetic pertur…
