Motion generates entanglement

Year: 2012

Type: article

Abstract: We demonstrate entanglement generation between mode pairs of a quantum field in a single, rigid cavity that moves nonuniformly in Minkowski space-time. The effect is sensitive to the initial state, the choice of the mode pair and bosonic versus fermionic statistics, and it can be stronger by orders of magnitude than the entanglement degradation between an inertial cavity and a nonuniformly moving cavity. Detailed results are given for massless scalar and spinor fields in ($1+1$) dimensions. By the equivalence principle, the results model entanglement generation by gravitational effects.
