Spectral representation of the particle production out of equilibrium—Schwinger mechanism in pulsed electric fields

We develop a formalism to describe the particle production out of equilibrium in terms of dynamical spectral functions, i.e. Wigner transformed Pauli–Jordanʼs and Hadamardʼs functions. We take an explicit example of a spatially homogeneous scalar theory under pulsed electric fields and investigate t...
