SUMMARY:The Penrose Inequality as a Constraint on Low Energy Quantum Gravity
DESCRIPTION:Swampland Seminar\n\nSpeaker: Aasmund Folkestad (MIT)\n\n\nTitle: The Penrose Inequality as a Constraint on Low Energy Quantum Gravity\n\nAbstract: In this talk\, I argue that the Penrose inequality (PI) can be used to constrain low energy theories compatible AdS/CFT\, and possibly also quantum gravity in flat space. Focusing on AdS/CFT\, it is shown that the PI can be violated for minimally coupled scalar fields\, and I produce exclusion plots on couplings that respect the PI. I also present numerical evidence that top-down scalar theories and supersymmetric theories respect the PI. Finally\, similar to the Breitenlohner-Freedman bound\, I give a necessary condition for the stability AdS that constrains coupling constants (beyond the scalar mass).
