Entanglement Entropy of Free Fermions in Timelike Slices
Bowei Liu, Hao Chen, Biao Lian
We define the entanglement entropy of free fermion quantum states in an arbitrary spacetime slice of a discrete set of points, and particularly investigate timelike (causal) slices…

Conserved Quantities from Entanglement Hamiltonian
Biao Lian
We show that the subregion entanglement Hamiltonians of excited eigenstates of a quantum many-body system are approximately linear combinations of subregionally (quasi)local approx…
