Description
We derive a phase-space representation of non-relativistic and relativistic quantum fields by expanding the field operator in terms of a set of localized wave packets. The corresponding probability amplitude depends on mean position and momentum of each wave packet, which serve as phase space coordinates. The dynamical equation of the probability amplitude takes the form of a classical Vlasov equation with quantum corrections. We discuss applications of the method, including Schwinger and Unruh effect, and link the results to the locality problem of relativistic quantum fields.
