Journal ArticleDOI
Harmonic coordinate method for simulating generic singularities
TL;DR: In this paper, a numerical method for general relativity and an application of that method are presented, which involves the use of harmonic coordinates in a 3+1 code to evolve the Einstein equations with scalar field matter.
Journal ArticleDOI
Rapid Thermalization in Field Theory from Gravitational Collapse
TL;DR: In this article, the authors investigated the system numerically and established that for small values of the initial amplitude of the scalar field there is no black hole formation, rather, the system performs an oscillatory motion typical of geodesics in AdS.
Journal ArticleDOI
An electromagnetic analogue of gravitational wave memory
TL;DR: In this paper, an electromagnetic analogue of gravitational wave memory is presented, where the authors consider what change has occurred to a detector of electromagnetic radiation after the wave has passed rather than a distortion in the detector, as occurs in the gravitational wave case.
Journal ArticleDOI
Perturbative and gauge invariant treatment of gravitational wave memory
TL;DR: In this article, a perturbative treatment of gravitational wave memory is presented, which leads to a type of gauge invariance in perturbation theory, which is more clear when expressed in terms of manifestly gauge invariant quantities rather than the perturbed metric.
Journal ArticleDOI
On field theory thermalization from gravitational collapse
TL;DR: In this paper, the authors investigated the time and radius of the apparent horizon formed as functions of the initial Gaussian profile for the scalar field and comment on several aspects of the dual field theory picture.
