摘要:

对于LC电路量子化方案所得到的哈密顿量,采用有序算符内的积分技术(IWOP技术)进行分析与讨论了在电容、电感、外源流在突变时所产生的量子压缩效应,结果表明:电容突变反映在正交相 呈现压缩效应;电感突变反映在另一正交相 呈现压缩效应;而外源流的非线性突变反映出来的是数—相压缩。

Abstract:

For mesoscopic L-C electric circuit we explore quantum squeezing respectively caused by abrupt change of capacity, inductance and external current source. It turns out that while the sudden change of capacity results in squeezing in the quadrature q, the sudden change of inductance brings out squeezing in another quadrature p, and the nonlinear change of enternal current source reveals number-phase squeezing.

Key words: quantum optics, mesoscopic LC electric circuit, number-phase-difference quantization, quantum squeezed
