Thermodynamic Remnants in Black-hole Evaporation
Ivan Arraut, Abhishek Kumar Mehta
We show that black-hole remnant scenario naturally arises in the original computations of Hawking without extra assumptions.
Path Integral approach to Black-hole Evaporation and Accretion
Ivan Arraut, Abhishek Kumar Mehta
In this paper, we investigate evaporation and accretion of uncharged, non-rotating, spherically symmetric black-holes from the path integral perspective. We show that the effective…
Heat Kernel methods in the first-order formalism
Abhishek Kumar Mehta
In this paper, we extend the heat kernel methods to the first-order formalism of gravity, specifically, in the language of differential forms. This allows us to compute the effecti…
Breaching the light barrier without paradoxes
Abhishek Kumar Mehta
In this paper, we propose the regularization principle that resolves the temporal paradoxes associated with faster-than-light particles or tachyons at the macroscopic scale. The pr…
Necessity of Quantizable Geometry for Quantum Gravity
Abhishek Kumar Mehta
In this paper, Dirac Quantization of gravity in the first-order formalism is attempted where instead of quantizing the connection and triad fields, the connection and the tria…
Gateway-like absurdly-benign traversable wormhole solutions
Abhishek Kumar Mehta
A class of wormhole solutions is constructed that has restricted polar degrees of freedom to achieve a gateway-like configuration. This compels the use of distribution-valued metri…
