PT对称有源LRC电路的实验研究
Experimental Study of Active LRC Circuits with PT-Symmetries
摘要：
一对有源LRC电路的相互耦合模式，一个具有放大作用，另一个具有等效的衰减量，提供了一个实验实现的一类系统，其中增益/损耗机制打破厄米性，同时保持奇偶校验时间PT对称性。对于增益/损耗强度参数的值PT，本征频率经历从实值到复值的自发相变，而简正模合并获得确定的手征性。时空能量演化的相变的后果也被提出。
英文摘要：
Mutually coupled modes of a pair of active LRC circuits, one with amplification and another with an equivalent amount of attenuation, provide an experimental realization of a wide class of systems where gain/loss mechanisms break the Hermiticity while preserving parity-time PT symmetry. For a value PT of the gain/loss strength parameter the eigen-frequencies undergo a spontaneous phase transition from real to complex values, while the normal modes coalesce acquiring a definite chirality. The consequences of the phase-transition in the spatiotemporal energy evolution are also presented.
