The Schrödinger–Newton equation and its foundations
New Journal of Physics, 2014 The necessity of quantising the gravitational field is still subject to an open debate. In this paper we compare the approach of quantum gravity, with that of a fundamentally semi-classical theory of gravity, in the weak-field non-relativistic limit.

Classical and quantum equations of motion of an n-dimensional BTZ black hole
Physics Letters B, 2016 We investigate the gravitational collapse of a non-rotating n-dimensional BTZ black hole in AdS space in the context of both classical and quantum mechanics.

European Physical Journal C: Particles and FieldsIn this article, we have studied some new facets of gravitational collapse, beyond conventional notions of black holes, and naked singularities. The present work is focused on the unresolved problems of theoretical physics concerning the final fate of ...

Gravitational-wave and Gravitational-wave Memory Signatures of Core-collapse Supernovae
The Astrophysical JournalIn this paper, we calculate the energy, signal-to-noise ratio (SNR), detection range, and angular anisotropy of the matter, matter memory, and neutrino memory gravitational-wave (GW) signatures of 21 three-dimensional initially nonrotating core-collapse ...

Gravitational Collapse of Massless Fields in an Expanding Universe
EPJ Web of Conferences, 2018 Gravitational collapse of a massless scalar field with the periodic boundary condition in a cubic box is reported. This system can be regarded as a lattice universe model.

Gravitational collapse of vacuum gravitational field configurations
Journal of Mathematical Physics, 1995 This paper proves a theorem about the existence of an apparent horizon in general relativity, which applies equally well to vacuum configurations and matter configurations. The theorem uses the reciprocal of the surface-to-volume ratio of a region on a space slice to measure the radius of the region, and uses the minimum value Kmin of certain ...
