Entanglement Entropy of Mixed State in Thermal CFT$_2$

High Energy Physics - Theory 2025-09-01 v3

Abstract

Using the subtraction approach, we give the bipartite mixed state entanglement entropy in thermal CFT2\text{CFT}_2. With these entanglement entropies, we examine in detail the holographic duals of different entangling configurations unambiguously. In the thermofield double state, we show a horizon-crossing feature in two-sided entanglement configuration.
