Quantum Bubble Dynamics in 2+1 Dimensional Gravity I: Geometrodynamic Approach
H. Zaidi, J. Gegenberg
The Dirac quantization of a 2+1 dimensional bubble is performed. The bubble consists of a string forming a boundary between two regions of space-time with distinct geometries. The…
Exact Dirac Quantization of All 2-D Dilaton Gravity Theories
D. Louis- Martinez, J. Gegenberg, G. Kunstatter
The most general dilaton gravity theory in 2 spacetime dimensions is considered. A Hamiltonian analysis is performed and the reduced phase space, which is two dimensional, is expli…
Loop Variables in Topological Gravity
Y. Bi, J. Gegenberg
We examine the relationship between covariant and canonical (Ashtekar/Rovelli/Smolin) loop variables in the context of BF type topological field theories in 2+1 and 3+1 dimensions,…
The Partition Function for Topological Field Theories
J. Gegenberg, G. Kunstatter
We use a Hodge decomposition and its generalization to non-abelian flat vector bundles to calculate the partition function for abelian and non- abelian BF theories in dimension…
Quantum Theory of Black Holes
J. Gegenberg, G. Kunstatter
A solvable 2-dimensional conformally invariant midi-superspace model for black holes is obtained by imposing spherical symmetry in 4-dimensional conformally invariant Einstein grav…
