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…
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…
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.
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…
