Holography and entanglement entropy
Entanglement entropy is an interesting computable in both quantum information and more generally in condensed matter systems. In recent years gauge/gravity duality has been used to calculate entanglement entropy for a wide range of strongly coupled quantum field theories. This talk will discuss how entanglement entropy is calculated, what features of the QFT it captures, and what entanglement entropy might teach us about RG flows in quantum field theories. A particular focus will be on providing a clean definition of renormalised entanglement entropy.
