论文摘要
我们考虑标量波背景$ ϕ（T-X）$中的二维Yukawa理论。如果一个人在这种背景下以初始状态为初始状态，则标量真空对应于$ ϕ = 0 $，则循环校正与Keldysh繁殖器的某个部分，对应于异常期望值，随时间增长。这表明，在$ ϕ（T-X）$ WAVE的踢球下，标量场将有效电位从$ ϕ = 0 $位置降低到适当的基态状态。我们显示了支持这些观察结果的证据。
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, grow with time. That is a signal to the fact that under the kick of the $ϕ(t-x)$ wave the scalar field rolls down the effective potential from the $ϕ=0$ position to the proper ground state. We show the evidence supporting these observations.
