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 …

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 …

Charged black rings at large D

B Chen, PC Li, Z Wang - Journal of High Energy Physics, 2017 - Springer
A bstract We study the charged slowly rotating black holes in the Einstein-Maxwell theory in
the large dimensions (D). By using the 1/D expansion in the near regions of the black holes …

An Action for and Hydrodynamics from the improved Large D membrane

Y Dandekar, S Kundu, S Mazumdar, S Minwalla… - Journal of High Energy …, 2018 - Springer
A bstract It has recently been demonstrated that black hole dynamics at large D is dual to the
motion of a probe membrane propagating in the background of a spacetime that solves …

Nonrelativistic Corners of Supersymmetric Yang-Mills Theory

T Harmark, N Wintergerst - Physical Review Letters, 2020 - APS
We show that N= 4 supersymmetric-Yang-Mills (SYM) theory on R× S 3 with gauge group
SU (N) is described in a near-BPS limit by a simple lower-dimensional nonrelativistic field …

Forced fluid dynamics from blackfolds in general supergravity backgrounds

J Armas, J Gath, V Niarchos, NA Obers… - Journal of High Energy …, 2016 - Springer
A bstract We present a general treatment of the leading order dynamics of the collective
modes of charged dilatonic p-brane solutions of (super) gravity theories in arbitrary …

Stationary solutions from the large D membrane paradigm

M Mandlik, S Thakur - Journal of High Energy Physics, 2018 - Springer
A bstract It has recently been shown that the dynamics of black holes in large number of
dimensions D can be recast as the dynamics of a probe membrane propagating in the …

Gravitational tension, spacetime pressure and black hole volume

J Armas, NA Obers, M Sanchioni - Journal of High Energy Physics, 2016 - Springer
A bstract We study the first law of black hole thermodynamics in the presence of surrounding
gravitational fields and argue that variations of these fields are naturally incorporated in the …

Black holes and biophysical (mem)-branes

J Armas, T Harmark - Physical Review D, 2014 - APS
We argue that the effective theory describing the long-wavelength dynamics of black branes
is the same effective theory that describes the dynamics of biophysical membranes. We …
