Non-marginal LTB-like models with inverse triad corrections from loop quantum gravity (2009)
Bojowald, Martin, Reyes, Juan D., Tibrewala, Rakesh
Marginal LTB models with corrections from loop quantum gravity have recently been studied with an emphasis on potential singularity resolution. This paper corroborates and extends the analysis in two...
Lemaitre-Tolman-Bondi collapse from the perspective of loop quantum gravity (2008)
Bojowald, Martin, Harada, Tomohiro, Tibrewala, Rakesh
Lemaitre-Tolman-Bondi models as specific spherically symmetric solutions of general relativity simplify in their reduced form some of the mathematical ingredients of black hole or cosmological...
Vaz, Cenalo, Tibrewala, Rakesh, Singh, T. P.
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 formation of trapped...
Classical and Quantum Gravitational Collapse in d-dim AdS Spacetime I. Classical Solutions (2007)
Tibrewala, Rakesh, Gutti, Sashideep, Singh, T. P., Vaz, Cenalo
We study the collapse of a spherically symmetric dust distribution in $d$-dimensional AdS spacetime. We investigate the role of dimensionality, and the presence of a negative cosmological constant,...
Quantum Mechanics without spacetime V - Why a quantum theory of gravity should be non-linear- (2005)
Singh, T. P., Gutti, Sashideep, Tibrewala, Rakesh
If there exists a formulation of quantum mechanics which does not refer to a background classical spacetime manifold, it then follows as a consequence, (upon making one plausible assumption), that a...
