Abstract:
In this paper we discuss behaviors of entanglement entropy between two interacting CFTs and its holographic interpretation using the AdS/CFT correspondence. We explicitly perform analytical calculations of entanglement entropy between two free scalar Ãeld theories which are interacting with each other in both static and time-dependent ways. We also conjecture a holographic calculation of entanglement entropy between two interacting N=4 super Yang-Mills by introducing a minimal surface in the S5 direction, instead of the AdS5 direction. This leads to an idea of generalized holographic entanglement entropy.
