Quantum mechanical effects of a gravitational collapse

In classical general relativity, singularity is considered as the inevitable outcome of a gravitational collapse. In this talk, I will discuss gravitational collapse using the semi-classical Schrödinger functional formalism. We have investigated the end stages of a quantum gravitational collapse and have found that due to quantum mechanical effects, the dynamical equation that governs the time evolution of the system becomes non-local and removes the singularity. Further, we examined the radiation emitted during the gravitational collapse with respect to both asymptotic and infalling observers and found that the emitted radiation is non-thermal with significant correlations among the emitted particles. Our work is likely to have implications in the resolution of the information loss paradox.
