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.
The cosmological constant emerging from a symmetry invariant
Ivan Arraut
The cosmological constant is normally introduced as an additional term entering the Einstein-Hilbert (EH) action. In this letter we demonstrate that instead, it appears naturally f…
On the Local equivalence of the Black Scholes and the Merton Garman equations
Ivan Arraut
It was demonstrated previously that the stochastic volatility emerges as the gauge field necessary for restoring the local symmetry under changes of the prices of the stocks inside…
