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) …

All holographic systems have scar states

A Milekhin, N Sukhov - Physical Review D, 2024 - APS
Scar states are special finite-energy density, but nonthermal states of chaotic Hamiltonians.
We argue that all holographic quantum field theories, including N= 4 super Yang-Mills, have …

Islands of stability and recurrence times in AdS

SR Green, A Maillard, L Lehner, SL Liebling - Physical review D, 2015 - APS
We study the stability of anti–de Sitter (AdS) spacetime to spherically symmetric
perturbations of a real scalar field in general relativity. Further, we work within the context of …

Collapse and nonlinear instability of AdS space with angular momentum

MW Choptuik, ÓJC Dias, JE Santos, B Way - Physical Review Letters, 2017 - APS
We present a numerical study of rotational dynamics in AdS 5 with equal angular momenta
in the presence of a complex doublet scalar field. We determine that the endpoint of …

AdS nonlinear instability: moving beyond spherical symmetry

OJC Dias, JE Santos - Classical and Quantum Gravity, 2016 - iopscience.iop.org
Abstract Anti-de Sitter (AdS) is conjectured to be nonlinear unstable to a weakly turbulent
mechanism that develops a cascade towards high frequencies, leading to black hole …

A hidden symmetry of AdS resonances

Holographic quenches in a confined phase

RC Myers, M Rozali, B Way - Journal of Physics A: Mathematical …, 2017 - iopscience.iop.org
We investigate quenches of holographic theories in a confined phase, where the energy
injected is insufficient to reach the deconfined phase. In such quenches, thermalization is …
