Quantum Penrose Inequality
Time: 2:00 pm
Place: For zoom link, sign up at:
Speaker: Marija Tomašević, Universitat de Barcelona
Abstract: According to the classical Penrose inequality, the mass at spatial infinity is bounded from below by a function of the area of certain trapped surfaces. We exhibit quantum field theory states that violate this relation at the semiclassical level. We formulate a Quantum Penrose Inequality by replacing the area with the generalized entropy of the light-sheet of an appropriate quantum trapped surface. We perform a number of nontrivial tests of our proposal, and we consider and rule out alternative formulations. We also discuss the relation to weak cosmic censorship.
Host: Lars Aalsma
