# Entanglement Entropy of the Dirac Field

40th LQP Workshop "Foundations and Constructive Aspects of QFT"
Onirban Islam on June 24, 2017

We compute an upper bound for the relative entanglement entropy of the ground state of the massive Dirac field on a static spacetime. This entanglement measure is bounded by an exponential decay for apart regions in a spacelike compact Cauchy hypersurface.
