Non-Minimally Coupled Scalar Field, Area Quantization and Black Hole Entropy
Sahil Devdutt, Akriti Garg, Ayan Chatterjee
The enumeration of black hole entropy in candidate theories of quantum gravity utilises the quantum properties of microstates residing on the black hole horizon. For example, in Lo…
Hawking radiation from black holes in 2+1 dimensions
Akriti Garg, Ayan Chatterjee
The paper develops a model to understand the effective quantum geometry of a black hole horizon and the emission of Hawking spectrum in dimensions. Using the algebra of Hamil…
Gravitational collapse of matter fields in de Sitter spacetimes
Akriti Garg, Ayan Chatterjee
In this paper, we discuss the spherically symmetric gravitational collapse of matter fields in the de Sitter universe. The energy-momentum tensor of the matter field is assumed to…
Spherical trapped surfaces in n-dimensional general relativity
Ayan Chatterjee, Suresh C. Jaryal, Akshay Kumar
In this paper, we examine gravitational collapse of matter fields in -dimensional general relativity. The matter energy-momentum tensor under consideration includes dust, perfec…
Gravitational collapse in pure Gauss- Bonnet theory
Akshay Kumar, Ayan Chatterjee, Suresh C. Jaryal
In this paper, we study the gravitational collapse of matter fields, which include dust, perfect fluids as well as fluids admitting bulk and shear viscosity. The initial conditions…
