Wormhole and Hawking Radiation

TL;DR

This paper demonstrates that in a two-dimensional dilaton gravity model, localized mass sources can form wormholes without singularities, and quantum effects produce Hawking radiation, potentially resolving the information loss paradox.

Contribution

It introduces a model where wormholes form classically from localized sources without singularities and incorporates quantum effects to generate Hawking radiation.

Findings

Wormholes can form classically without singularities in this model.

Quantum corrections lead to Hawking radiation.

Potential resolution of the information loss paradox.

Abstract

It is shown in a variant of two dimensional dilaton gravity theories that an arbitrary, localized massive source put in an initially regular spacetime gives rise to formation of the wormhole classically, without accompanying the curvature singularity. The semiclassical quantum correction under this wormhole spacetime yields Hawking radiation. It is expected, with the quantum back reaction added to the classical equation, that the information loss paradox may be resolved in this model.
