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,…
Particles as Wilson lines of gravitational field
L. Freidel, J. Kowalski--Glikman, A. Starodubtsev
Since the work of Mac-Dowell-Mansouri it is well known that gravity can be written as a gauge theory for the de Sitter group. In this paper we consider the coupling of this theory…
String theory in a vertex operator representation: a simple model for testing loop quantum gravity
Artem Starodubtsev
The loop quantum gravity technique is applied to the free bosonic string. A Hilbert space similar to loop space in loop quantum gravity as well as representations of diffeomorphism…
