The spectrum of states of Ba~nados-Teitelboim-Zanelli black hole formed by a collapsing dust shell
Alexander A. Andrianov, Danila Lyozin, Artem Starodubtsev
We perform canonical analysis of an action in which 2+1-dimensional gravity with negative cosmological constant is coupled to cylindrically symmetric dust shell. The resulting phas…
Quantum Analysis of BTZ Black Hole Formation Due to the Collapse of a Dust Shell
Alexander A. Andrianov, Artem Starodubtsev, Yasser Elmahalawy
We perform Hamiltonian reduction of a model in which 2+1 dimensional gravity with negative cosmological constant is coupled to a cylindrically symmetric dust shell. The resulting a…
Cylindrically symmetric 2+1 gravity in terms of global variables:quantum dynamics
Alexander A. Andrianov, Yasser Elmahalawy, Artem Starodubtsev
We perform quantization of a model in which gravity is coupled to a circular dust shell in 2+1 spacetime dimensions. Canonical analysis shows that momentum space of this model is A…
2+1-dimensional gravity coupled to a dust shell: quantization in terms of global phase space variables
Alexander Andrianov, Yasser Elmahalawy, Artem Starodubtsev
We perform canonical analysis of a model in which gravity is coupled to a spherically symmetric dust shell in 2+1 spacetime dimensions. The result is a reduced action depending on…
Effective particle kinematics from Quantum Gravity
Jerzy Kowalski-Glikman, Artem Starodubtsev
Particles propagating in de Sitter spacetime can be described by the topological BF $\SO(4,1)$ theory coupled to point charges. Gravitational interaction between them can be introd…
Can we see gravitational collapse in (quantum) gravity perturbation theory?
J. Kowalski-Glikman, A. Starodubtsev
In this paper, by making use of the perturbative expansion around topological field theory we are trying to understand why the standard perturbation theory for General Relativity,…
