AI总结:

本文研究了两个探测波导对超拉曼过程动力学的影响,将探测波导通过倏逝波相互作用导致的演化增强或减弱分别视为量子anti-Zeno和Zeno效应,发现该效应与相位匹配或失配相关,但与玻色子模式的反聚束现象无关。

摘要:

本文从量子Zeno与anti-Zeno效应的角度,研究了两个探测波导的存在对超拉曼过程动力学的影响。具体而言,由于通过倏逝波与探测波导发生相互作用,超拉曼过程演化的增强(减弱)被视为量子anti-Zeno(Zeno)效应。我们考虑了两个探测波导每次仅与一个光学模式发生相互作用。例如,在一种特定情形下,假设两个非简并泵浦模式与每个探测波导发生线性相互作用,而Stokes和anti-Stokes模式不与探测波导相互作用。类似地,在另一种情形下,我们假设两个探测波导同时与Stokes(anti-Stokes)模式发生相互作用。目前的结果表明,量子Zeno(anti-Zeno)效应与相位匹配(失配)相关。然而,我们并未发现超拉曼过程中存在的量子Zeno效应与玻色子模式中的反聚束现象之间存在任何关系。

英文摘要:

The effect of the presence of two probe waveguides on the dynamics of hyper-Raman processes is studied in terms of quantum Zeno and anti-Zeno effects. Specifically, the enhancement (diminution) of the evolution of the hyper-Raman processes due to interaction with the probe waveguides via evanescent waves is viewed as quantum Zeno (anti-Zeno) effect. We considered the two probe waveguides interacting with only one of the optical modes at a time. For instance, as a specific scenario, it is considered that the two non-degenerate pump modes interact with each probe waveguide linearly while Stokes and anti-Stokes modes do not interact with the probes. Similarly, in another scenario, we assumed both the probe waveguides interact with Stokes (anti-Stokes) mode simultaneously. The present results show that quantum Zeno (anti-Zeno) effect is associated with phase-matching (mismatching). However, we did not find any relation between the presence of the quantum Zeno effect and antibunching in the bosonic modes present in the hyper-Raman processes.
