摘要
根据量子不变量理论,同时考虑介观电容器极板间电子波函数的耦合作用和电路的耗散,研究介观RLC电路系统在交流电流源作用下动力学的演化过程,并且得到描述系统量子态随时间的演化算符.进一步的分析结果表明,介观RLC电路系统的波函数将由任意的初态演化到一般的压缩态.
According to the LR invariant theory, the mesoseopic RLC circuit driven by a alternating current source was discussed. The mutual coupling of electron wave functions between the two plates of capacitor and the resistance of the circuit were taken into account. In our conclusion, the quantum states which dominate the dynamic property of the system and the time evolution operator of the mesoseopic circuit were obtained. The wave function of the mesoscopic RLC system will evolve from an arbitrary initial state to a generalized squeezed state.
