Unitarity From a Smooth Horizon?
Raphael Bousso, Marija Tomasevic
Under semiclassical evolution, black holes retain a smooth horizon but fail to return information. Yet, the Ryu-Takayanagi prescription computes the boundary entropy expected from…

Quantum Information Bound on the Energy
Raphael Bousso, Arvin Shahbazi-Moghaddam, Marija Tomasevic
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 th…

Quantum Penrose Inequality
Raphael Bousso, Arvin Shahbazi-Moghaddam, Marija Tomasevic
The classical Penrose inequality specifies a lower bound on the total mass in terms of the area of certain trapped surfaces. This fails at the semiclassical level. We conjecture a…
