Journal ArticleDOI
Models of Wave-function Collapse, Underlying Theories, and Experimental Tests
TL;DR: In this article, a review is given of an experimentally falsifiable phenomenological proposal, known as continuous spontaneous collapse, which is a stochastic nonlinear modification of the Schrodinger equation.
Journal ArticleDOI
Quantum gravitational corrections to the functional Schrodinger equation
Claus Kiefer,Tejinder P. Singh +1 more
TL;DR: In this paper, the authors derive corrections to the Schrodinger equation which arise from the quantization of the gravitational field, achieved through an expansion of the full functional Wheeler-DeWitt equation with respect to powers of the gravitation constant.
Journal ArticleDOI
The possibility of cosmic acceleration via spatial averaging in Lemaitre-Tolman-Bondi models
TL;DR: In this paper, the authors investigate the possible occurrence of a positive cosmic acceleration in a spatially averaged, expanding, unbound Lema?tre?Tolman?Bondi cosmology.
Journal ArticleDOI
The final fate of spherical inhomogeneous dust collapse
TL;DR: In this paper, the role of the initial density and velocity distributions in the collapse of a spherically symmetric inhomogeneous dust cloud is examined, in a general manner, and it is shown that the collapse can end in either a black hole or a naked singularity, depending on the initial parameters characterizing these profiles.
Journal ArticleDOI
Role of initial data in the gravitational collapse of inhomogeneous dust.
TL;DR: It is found that the end state of the collapse of a spherically symmetric inhomogeneous dust cloud described by the Tolman-Bondi models is either a black hole or a naked singularity, depending on the parameters of the initial density distribution.
