摘要研究了远离保形区域的若干相互作用量子场论模型中的全局猝灭。我们在单环水平上进行了微扰重整化，并跟踪重整化群流引起的淬火协议的修改。早期各种可观测值的标度在快速淬火速率下进行了评估，特别强调了不能使用有限阶共形摄动理论恢复的阶效应。我们采用有效作用的规范思想来验证我们的结果，并讨论了理解晚时间动力学的潜在途径。
A bstractWe study global quenches in a number of interacting quantum field theory models away from the conformal regime. We conduct a perturbative renormalization at one-loop level and track the modifications of the quench protocol induced by the renormalization group flow. The scaling of various observables at early times is evaluated in the regime of rapid quench rates, with a particular emphasis placed on the leading order effects that cannot be recovered using the finite order conformal perturbation theory. We employ the canonical ideas of effective action to verify our results and discuss a potential route towards understanding the late time dynamics.
