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.
