Abstract

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

CLC Number:
