Noncommutative gravity, a `no strings attached' quantum-classical duality, and the cosmological constant puzzle
T. P. Singh
There ought to exist a reformulation of quantum mechanics which does not refer to an external classical spacetime manifold. Such a reformulation can be achieved using the language…
Classical and Quantum Gravitational Collapse in d-dim AdS Spacetime II. Quantum States and Hawking Radiation
Cenalo Vaz, Rakesh Tibrewala, T. P. Singh
In a previous paper we studied the collapse of a spherically symmetric dust distribution (marginally bound LTB) in d-dimensional AdS spacetime and obtained the condition for the fo…
Mass Spectrum and Statistical Entropy of the BTZ black hole from Canonical Quantum Gravity
Cenalo Vaz, Sashideep Gutti, Claus Kiefer +2
In a recent publication we developed a canonical quantization program describing the gravitational collapse of a spherical dust cloud in 2+1 dimensions with a negative cosmological…
Classical and Quantum Gravitational Collapse in d-dim AdS Spacetime I. Classical Solutions
Rakesh Tibrewala, Sashideep Gutti, T. P. Singh +1
We study the collapse of a spherically symmetric dust distribution in -dimensional AdS spacetime. We investigate the role of dimensionality, and the presence of a negative cosmo…
Quantum Gravitational Collapse and Hawking Radiation in 2+1 Dimensions
Cenalo Vaz, Sashideep Gutti, Claus Kiefer +1
We develop the canonical theory of gravitational collapse in 2+1 dimensions with a negative cosmological constant and obtain exact solutions of the Wheeler--DeWitt equation regular…
The inevitable nonlinearity of quantum gravity falsifies the many-worlds interpretation of quantum mechanics
T. P. Singh
There are fundamental reasons as to why there should exist a reformulation of quantum mechanics which does not refer to a classical spacetime manifold. It follows as a consequence…
