Quantum correlations in a gravitational collapse simulation with SpheriCo.jl
Benjamin Berczi, Magdalena Eriksson, Thanasis Giannakopoulos +1
We report on work using a newly developed code, SpheriCo.jl, that computes the gravitational collapse of a spherical scalar field, where the scalar can be either a classical field,…
Characteristic formulations of general relativity and applications
Thanasis Giannakopoulos
General relativity can describe various gravitational systems of astrophysical relevance, like black holes and neutron stars, or even strongly coupled systems through the holograph…
Numerical convergence of model Cauchy-characteristic extraction and matching
Thanasis Giannakopoulos, Nigel T. Bishop, David Hilditch +2
Gravitational waves provide a powerful enhancement to our understanding of fundamental physics. To make the most of their detection we need to accurately model the entire process o…
Gauge structure of the Einstein field equations in Bondi-like coordinates
Thanasis Giannakopoulos, Nigel T. Bishop, David Hilditch +2
The characteristic initial (boundary) value problem has numerous applications in general relativity (GR) involving numerical studies, and is often formulated using Bondi-like coord…
Hyperbolicity of General Relativity in Bondi-like gauges
Thanasis Giannakopoulos, David Hilditch, Miguel Zilhao
Bondi-like (single-null) characteristic formulations of general relativity are used for numerical work in both asymptotically flat and anti-de Sitter spacetimes. Well-posedness of…
