High Energy Theory seminar: "Boundary conditions, zero modes, and spacetime entropy"
James Sully, University of British Columbia
How do we describe the local Hilbert space of a continuum field theory? And does this have lessons to teach us about the emergence of spacetime in AdS/CFT? I will describe how to define the Hilbert space of an interval in a 2D CFT without turning to abstruse mathematics. For CFTs with a gravitational dual, this leads to a theory of gravitational membranes and new insights for understanding spacetime entropy.
