Minkowski vacuum in Rindler spacetime and Unruh thermal state for Dirac fields

Abstract

We consider a free Dirac field in flat spacetime and we derive the representation of the Minkowski vacuum as an element of the Rindler-Fock space. We also compute the statistical operator obtained by tracing away the left wedge. We detail the resulting thermal state for fermionic particles.
