Title: Lessons for Gravity from Entanglement
Date: Thu, Apr 09, 2015, 11:45 - 13:15
Place: Seminar Room B
Abstract: Entanglement is a fundamental physical property of all quantum systems. It serves as an intersecting point between different subfields of physics. From AdS/CFT point of view quantum entanglement connects geometry with quantum information, providing a window to understand how the bulk gravity physics emerges from the holographic field theoretic point of view. Probing some aspects of this connection is the broad theme of this talk.
In this talk I will review holographic entanglement for Einstein gravity and generalization of it for various higher derivative gravity theories and discuss some subtle issues for higher derivative theories, specifically its striking similarity with the black hole entropy and the connection with Wald entropy for higher derivative gravity theories. Also I will discuss how to put some constraints on gravity theories and probe RG flow in the context of holography using the concept entanglement.
