Description
Entanglement is a defining property of quantum physics and provides a natural way to characterize correlations. Despite some inherent difficulties, there has been considerable advancement in lattice evaluations of entanglement measures, such as entanglement entropy (EE), in QFTs.
In my poster, I will present our argument that, in certain attainable limits, a derivative of EE approaches the thermal entropy density for general QFTs. We provide validation for these claims from our lattice computations in 3d O(4) scalar field theory by showing that in the corresponding limits, the EE derivative satisfies the same Maxwell relation as the thermal entropy density. These results represent a first step towards extracting thermodynamics from lattice evaluations of EE in QCD and other more complicated QFTs.
