Event Details

Entanglement entropy plays an important role in recent theoretical developments, from classifying topological phases of matter to the understanding of the emergence of spacetime in AdS/CFT. In this talk, Dr. Mezei will explore the shape dependence of entanglement entropy in the ground state of a CFT. Based on these results he proposes that the sphere minimizes the universal part of entanglement entropy among all shapes. Such a minimization result contextualizes the fruitful relation between the entanglement entropy of a sphere and the number of degrees of freedom in a field theory, which he reviews.
