State-dependent divergences in the entanglement entropy

Year: 2016

Type: article

Abstract: We show the entanglement entropy in certain quantum field theories to contain state-dependent divergences. Both perturbative and holographic examples are exhibited. However, quantities such as the relative entropy and the generalized entropy of black holes remain finite, due to cancellation of divergences. We classify all possible state-dependent entanglement entropy divergences that can appear in both perturbatively renormalizeable and holographic covariant d ≤ 6 quantum field theories.
