Modular Hamiltonian for Excited States in Conformal Field Theory
We present a novel replica trick that computes the relative entropy of two arbitrary states in conformal field theory. Our replica trick is based on the analytic continuation of partition functions that break the Z[subscript n] replica symmetry. It provides a method for computing arbitrary matrix el...
