Quantum thermodynamics of an M2-M5 brane system

B Pourhassan, H Aounallah, M Faizal… - Journal of High Energy …, 2022 - Springer
A bstract We will investigate a system of M2-M5 branes as a black M2-M5 bound state. The
behavior of this system will be investigated at short distances. At such scales, we will have to …

New asymptotically (anti)-de Sitter black holes in (super) gravity

J Armas, GP Nicosia - Journal of High Energy Physics, 2024 - Springer
A bstract We use the duality between gravitational dynamics and fluids living on dynamical
surfaces carrying multiple charges, known as the blackfold approach, to perturbatively …

Newton-Cartan submanifolds and fluid membranes

J Armas, J Hartong, E Have, BF Nielsen, NA Obers - Physical Review E, 2020 - APS
We develop the geometric description of submanifolds in Newton-Cartan spacetime. This
provides the necessary starting point for a covariant spacetime formulation of Galilean …

Rings, ripples, and rotation: connecting black holes to black rings

OJC Dias, JE Santos, B Way - Journal of High Energy Physics, 2014 - Springer
A bstract Singly-spinning Myers-Perry black holes in d≥ 6 spacetime dimensions are
unstable for sufficiently large angular momentum. We numerically construct (in d= 6 and d …

Derivation of the blackfold effective theory

J Camps, R Emparan - Journal of High Energy Physics, 2012 - Springer
A bstract We study fluctuations and deformations of black branes over length scales larger
than the horizon radius. We prove that the Einstein equations for the perturbed p-brane …

Gravitational double layers

JMM Senovilla - Classical and Quantum Gravity, 2014 - iopscience.iop.org
I analyze the properties of thin shells through which the scalar curvature R is discontinuous
in gravity theories with Lagrangian F (R)= R− 2Λ+ αR 2 on the bulk. These shells/domain …

How fluids bend: the elastic expansion for higher-dimensional black holes

J Armas - Journal of High Energy Physics, 2013 - Springer
