Numerical methods for finding stationary gravitational solutions

ÓJC Dias, JE Santos, B Way - Classical and Quantum Gravity, 2016 - iopscience.iop.org
The wide applications of higher dimensional gravity and gauge/gravity duality have fuelled
the search for new stationary solutions of the Einstein equation (possibly coupled to matter) …

Carrollian fluids and spontaneous breaking of boost symmetry

J Armas, E Have - Physical Review Letters, 2024 - APS
In the hydrodynamic regime, field theories typically have their boost symmetry
spontaneously broken due to the presence of a thermal rest frame although the associated …

Generalized entropy and higher derivative Gravity

J Camps - Journal of High Energy Physics, 2014 - Springer
A bstract We derive an extension of the Ryu-Takayanagi prescription for curvature squared
theories of gravity in the bulk, and comment on a prescription for more general theories. This …

Hydrodynamics, spin currents and torsion

AD Gallegos, U Gürsoy, A Yarom - Journal of High Energy Physics, 2023 - Springer
A bstract We construct the canonical constitutive relations for a fluid description of a system
with a spin current, valid in an arbitrary number of dimensions in the absence of parity …

A charged membrane paradigm at large D

S Bhattacharyya, M Mandlik, S Minwalla… - Journal of High Energy …, 2016 - Springer
A bstract We study the effective dynamics of black hole horizons in Einstein-Maxwell theory
in a large number of spacetime dimensions D. We demonstrate that horizon dynamics may …

Ideal fracton superfluids

J Armas, E Have - SciPost Physics, 2024 - scipost.org
We investigate the thermodynamics of equilibrium thermal states and their near-equilibrium
dynamics in systems with fractonic symmetries in arbitrary curved space. By explicitly …

Holographic entanglement entropy and gravitational anomalies

A Castro, S Detournay, N Iqbal, E Perlmutter - Journal of High Energy …, 2014 - Springer
A bstract We study entanglement entropy in two-dimensional conformal field theories with a
gravitational anomaly. In theories with gravity duals, this anomaly is holographically …

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 …

Environmental bias and elastic curves on surfaces

J Guven, DM Valencia… - Journal of Physics A …, 2014 - iopscience.iop.org
The behavior of an elastic curve bound to a surface will reflect the geometry of its
environment. This may occur in an obvious way: the curve may deform freely along …

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 …
