标题： Non-perturbative method for particle detectors with continuous interactions

摘要： 我们证明，由脉冲耦合组成的探测器切换轮廓是一种有用的计算工具，可以高效地近似涉及连续切换函数的结果，无论是单个探测器还是多个探测器的设置。对于足够规则的切换，在微扰理论的所有阶数中快速收敛到连续结果意味着该工具可用于获得具有连续切换函数的一般粒子探测器现象的非微扰结果。 显示英文摘要

摘要： We show that detector switching profiles consisting of trains of delta couplings are a useful computational tool to efficiently approximate results involving continuous switching functions, both in setups involving a single detector and multiple ones. The rapid convergence to the continuous results at all orders in perturbation theory for sufficiently regular switchings means that this tool can be used to obtain non-perturbative results for general particle detector phenomena with continuous switching functions.
