介观含时电容耦合电路中压缩的产生及其在有限温度下的量子涨落

Generation of squeezing and the quantum fluctuations at finite temperatures in a mesoscopic time-dependent capacitive coupled circuit.

从电容和电感随时间变化的介观电容耦合电路的经典运动方程出发 ,在给定初始条件下 ,精确求解了电荷和电流涨落的时间演化规律 ,并考虑了温度对涨落的影响 .在这样的电路中可以产生压缩 。

Starting from the classical equations of motion of the electric circuit with time\|dependent inductance and capacity, under certain initial conditions,the exact evolution of the quantum fluctuations of the electric charge and current were obtained and the effect of temperature was considered.In such circuits,squeezing can be generated and the squeezing parameters are related to the physical quantities in the circuit.
