A quantum thin shell surrounding a Black Hole
Cenalo Vaz
In a previous work we obtained exact solutions for the proper time quantum mechanics of a thin dust shell, collapsing in a vacuum. We extend these results to the quantum collapse o…
Proper time Quantization of a Thin Shell
Cenalo Vaz
"Time" has different meanings in classical general relativity and in quantum theory. While all choices of a time function yield the same local classical geometries, quantum theorie…
Quantum Collapse of a Thin Shell Revisited
Cenalo Vaz
There are several possible choices of the time parameter for the canonical description of a self-gravitating thin shell, but quantum thories built on different time parameters lead…
Gravitationally Bound Bose Condensates with Rotation
Souvik Sarkar, Cenalo Vaz, L. C. R. Wijewardhana
We develop a self-consistent, Gravitoelectromagnetic (GEM) formulation of a slowly rotating, self-gravitating and dilute Bose-Einstein condensate (BEC), intended for astrophysical…
Canonical Chern-Simons Gravity
Souvik Sarkar, Cenalo Vaz
We study the canonical description of the axisymmetric vacuum in 2+1 dimensional gravity, treating Einstein's gravity as a Chern Simons gauge theory on a manifold with the restrict…
Quantum dust collapse in 2+1 dimensions
Souvik Sarkar, Cenalo Vaz, L. C. R. Wijewardhana
In this paper we will examine the consequence of a canonical theory of quantum dust collapse in 2+1 dimensions. The solution of the WDW equation describing the collapse indicates t…
