Title: Hawking radiation as quantum tunneling

Speaker: Takumi Hayashi

Abstract: Hawking radiation is a thermal radiation induced by a black hole, which is predicted by quantum field theory in curved spacetime. There are several attempts to formulate Hawking radiation as quantum tunneling of an emitted particle, which succeed in capturing the feature of it. Since the tunneling method is simpler than the original field theory, there exist important applications to the dynamical black hole providing an insight into information loss paradox.
In this talk, I will review the tunneling method of Hawking radiation and generalization to the case with back reaction to black hole. I will also briefly introduce the recent works which discuss the information loss on the basis of the method.
