Secularly growing loop corrections in scalar wave background
Abstract We consider two-dimensional Yukawa theory in the scalar wave background ϕ(t − x). If one takes as initial state in such a background the scalar vacuum corresponding to ϕ = 0, then loop corrections to a certain part of the Keldysh propagator, corresponding to the anomalous expectation value,...
