模拟量子Zeno和Anti-Zeno效应的经典开关LC/LR电路

A Classical Switched LC/LR Circuit Modeling the Quantum Zeno and Anti-Zeno Effects

T. Hubsch, V. Pankovic

摘要:

概括最近的分析,我们的量子芝诺和反芝诺效应与快速切换,理想的LC/LR电路,在限制的情况下,它交替非常多次之间的短LC和更短的LR制度。如果初始电流被设置为可以忽略不计,电容器就永远不会放电。如果使初始电流占主导地位,则该电容器放电,并且比它所限制的指数衰减更快。在这样一个基本的模型中,这些相的存在和简单性表明,相应的效应在整个物理学中是普遍存在的,无论是量子的还是经典的。反过来,这个模型的参数空间包含中间阶段,在这些阶段中,电路表现出的行为似乎预示着其他一些感兴趣的量子效应。

英文摘要:

Generalizing a recent analysis, we model the quantum Zeno and anti-Zeno effects with a quickly switched, ideal LC/LR circuit, in the limiting case of it alternating very many times between its short LC and even shorter LR regime. If the initial current is arranged to be negligible, the capacitor turns out never to discharge. If the initial current is made dominant, this capacitor discharges, and faster than the exponential decay to which it limits. The existence and simplicity of these phases in such a rudimentary model indicates that the corresponding effects are ubiquitous throughout physics, both quantum and classical. In turn, the parameter space of this model contains intermediate phases in which the circuit exhibits behaviors that seem to foreshadow other quantum effects of some interest.
