Title: Holographic Entanglement Entropy and Strong Subadditivity

Speaker: Dr. Jian-Yang He (何建阳) (Brandeis University, USA)

Time: 3:00PM, Jan. 16th (Thursday)

Place: Theoretical Physics Division，319

Abstract：

Entanglement entropy(EE) is a physical quantity measuring correlations in quantum systems. On the other hand, AdS/CFT correspondence provides us a new method to investigate EE from gravity theories. In this talk the speaker will give a brief review on holographic EE, in both field theory and gravity calculations. Some properties will be discussed and the speaker will focus on strong subadditivity inequality.
