Thermalization of Causal Holographic Information

Understand

We study causal wedges associated with a given sub-region in the boundary of asymptotically AdS spacetimes.

• Part of our motivation is to better understand the recently proposed holographic observable, causal holographic information (CHI), which is given by the area of a bulk co-dimension two surface lying on the boundary of the causal wedge.
• It has been suggested that CHI captures the basic amount of information contained in the reduced density matrix about the bulk geometry.
• To explore its properties further we examine its behaviour in time-dependent situations.
