交流源作用下介观串联RLC电路系统量子态随时间的演化
Time evolution of mesoscopic RLC circuit under a alternating voltage source
【摘要】 介观串联RLC电路系统在交流电压源的作用下,同时介观电容器极板间电子波函数的耦合作用和电路的耗散也考虑进来,由拉格朗日函数推导出系统的含时哈密顿量,根据量子不变量理论,系统的量子态将随时间演化到压缩态。分析结果表明,介观电路系统由任意的初态演化到一般的压缩态。
【Abstract】 The mesoscopic RLC circuit with a alternationg voltage source was discussed by quantum invariant theory. The mutual-couple energe and the dissipation were also taken into account. The Hamiltonian of the mesoscopic system was derived from Lagrangian function. The wave function of the system will evolve to a squeezed state as time elapses. In conclusion, the state of the system will evolve from a arbitrary initial state to a general squeezed state.
