Quantum chaos and quantum gravity

Date and Time: Wednesday, February 23, 2022, 03:30pm - 04:30pm
Location: Remote -

Speaker: Steve Shenker, Stanford University


Abstract: I will discuss some aspects of quantum chaos that are present in the physics of black holes.   In particular I will discuss how sensitive dependence on initial conditions, Lyapunov behavior, is realized in these systems and a closely connected universal bound on the size of the quantum Lyapunov exponent.  I will then turn to the behavior of the individual energy eigenvalues of quantum black holes.   In quantum chaotic systems these energies should behave like the eigenvalues of a random matrix, and I will discuss aspects of a gravitational explanation for this behavior in black holes.
