Effect of scalar condensation on fermionic pole-skipping
Published 2024-12-01“…Abstract In this paper, we investigated the holographic fermionic pole-skipping phenomena for a class of interacting theory in a charged AdS black hole background. We have studied two types of fermion-scalar interactions in the bulk: dipole and Yukawa type interaction. …”

A Note on Holography and Phase Transitions
Published 2011-01-01“…Focusing on the connection between the Landau theory of second-order phase transitions and the holographic approach to critical phenomena, we study diverse field theories in an anti de Sitter black hole background. Through simple analytical approximations, solutions to the equations of motion can be obtained in closed form which give rather good approximations of the results obtained using more involved numerical methods. …”

An Interior Solution for the Kerr Metric: A Novel Approach
Published 2025-01-01“…Our findings reveal anisotropic fluid properties and energy condition behaviors in specific space-time regions, providing insights into the strong-field regime of rotating black holes. The proposed solution offers a more realistic description of rotating black hole interiors, with implications for understanding compact astrophysical objects.…”

La topographie légendaire des itinéraires de la navette
Published 2015-06-01“…The commuter, the train and the route have been the object of a myth to serve a commercial policy as well as a development of the served cities.But the legend settled down only because it is one of the anthropological foundations and because the myth allows to combine incompatible elements, here the combination of the requirements of contemporary modernity and a more traditional life of provincial rooting.One of the aspects of the myth is that the TGV is a sterile environment and the countryside it goes through, a "black hole". Is it really the case ? Social practices and memory reinvest places and sometimes invent them. …”

Weak Minimal Area in Entanglement Entropy
Published 2015-01-01“…The necessary condition for the weak minimality is checked via Legendre test and its sufficient nature via Jacobi test. We show for AdS black hole with a strip type entangling region that it is this minimality condition that makes the hypersurface unable to cross the horizon, which is in agreement with that studied earlier by Engelhardt et al. and Hubeny using a different approach. …”
