Title: Generalized Real-space Chern Number Formula and Entanglement Hamiltonian
Speaker: Prof. Gu, Yingfei (Tsinghua University)

Place: Rm 401, 7th Buidling, UCAS Zhongguancun Campus (中关村东路80号7号楼401)

Abstract: 
In this talk, I will introduce two recent conjectures on extracting topological invariants from ground state using entanglement Hamiltonians. I will present a proof of these conjectures in the special case of Gaussian states, which involves a generalization of a real-space Chern number formula by Kitaev.
