报告摘要:

In this talk I will introduce some results about geometric states in the context of AdS/CFT. The holographic entanglement entropy is a useful way to understand the geometry in the bulk. Spectra of the reduced density matrix contain more information than entanglement entropy. I will show how to obtain the spectrum decomposition of the reduced density matrix by using Renyi entropy. I will also show how to construct the dual states of the so-called fixed area states. The results permit us to decompose the geometry as superposition of fixed area states. This gives us a new way to understand the quantum properties of geometry or spacetime.
