Abstract:
While quantum field theory in Minkowski spacetime relies on the notion of one particle states, the existence of such states has been controversial in the context of quantum field theory in curved spacetime. In this talk we argue that a notion of spin ½ one-particle state exists in general timedependent curved backgrounds. These particles are localized on two dimensional subspaces and in the flat spacetime limit simulate spin-up massless Dirac particles separated from their spin-down counterparts.
