Stable Black Strings from Warped Backgrounds
Sylvain Fichet, Eugenio Megias, Mariano Quiros +1
We show that spacetime curvature alone can classically stabilize black strings. Working within a consistent five-dimensional dilaton-gravity system with a flat brane, we find that…
Holographic Dark Matter
Sylvain Fichet, Eugenio Megias, Mariano Quiros
Cold dark matter may be a fluid (or plasma) residing in a strongly-interacting hidden sector, rather than a population of weakly-coupled particles. Such a scenario admits a hologra…
Gravity-Induced Photon Interactions and Infrared Consistency in any Dimensions
Pedro Bittar, Sylvain Fichet, Lucas de Souza
We compute the four-photon () operators generated by loops of charged particles of spin , , in the presence of gravity and in any spacetime dimension .…
Entanglement Entropy and Thermal Phase Transitions from Curvature Singularities
Sergio Barbosa, Sylvain Fichet, Eugenio Megias +1
We study holographic entanglement entropy and revisit thermodynamics and confinement in the dilaton-gravity system. Our analysis focuses on a solvable class of backgrounds that inc…
