Semi-classical Imprint of Horizon Induced Instability

Arnab Chakraborty, Onirban Islam, Arshad Momen

We consider an inverted harmonic oscillator in the space $L^{2} (S)$ of square-integrable functions on the circle $S$ and compute its density of states employing…

A Lorentzian Equivariant Index Theorem

Onirban Islam, Lennart Ronge

We develop a formula for the equivariant index of a twisted Dirac operator on a compact globally hyperbolic spacetime with timelike boundary on which a group acts isometrically, su…
