Theory Seminar (High Energy/Cosmology)
Quantum Penrose Inequality
Time: 2:00 pm - 3:00 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.

Department Coffee Hour
Time: 3:30 pm - 4:30 pm
Abstract: Join us weekly for an informal virtual coffee hour! Catch up with others in the department, tell us how things are going, and impress everyone with your Zoom background skills. Coffee Hour is open to any and all faculty, staff, and students in the department. Sometimes we have a topic, and we'll try to get that topic posted here in advance or sent out by email before each coffee hour.
