论文摘要
在矩阵乘积状态框架中，我们研究了一个两级系统的非马克维亚反馈动力学，该系统与半无限波导中的电磁场相互作用，在该系统中，在该波导中可以激发原子 - photon结合状态的激发。以发射极的稳态激发为优点，我们比较了最初激发的量子发射极的捕获激发，以及通过含有多达四个光子的量化脉冲制备的发射极。在后一种情况下，我们发现，对于大量反馈延迟时间，使用最初激发的发射极可能会产生比最初激发的发射极可能产生的稳态激发，因为刺激的发射过程可以增强捕获概率，而与最初激发的发射极的自发衰减相比。
Within the matrix product state framework, we study the non-Markovian feedback dynamics of a two-level system interacting with the electromagnetic field inside a semi-infinite waveguide where the excitation of an atom-photon bound state is possible. Taking the steady-state excitation of the emitter as a figure of merit, we compare the trapped excitation for an initially excited quantum emitter and an emitter prepared via quantized pulses containing up to four photons. In the latter case, we find that for large feedback delay times, multi-photon pulses can yield a significantly higher steady-state excitation than possible with an initially excited emitter since the stimulated emission process can enhance the trapping probability in comparison to the spontaneous decay of an initially excited emitter.
