| 摘 要： | 利用热场动力学的方法研究了介观RLC电路在有限温度下的相干态和压缩态中电荷和磁通量的量子涨落.结果表明,介观RLC电路中电荷和磁通量的量子涨落不仅与电路中的元件参数而且可能与环境温度和压缩参数有关,而这些量子涨落与平移参数无关.

| Abstract: | By thermo-field dynamics (TFD), we study the quantum fluctuations of charge and magnetic flux of a mesoscopic circuit including resistor, inductor and capacitor (RLC) in coherent states and squeezed states at finite temperature. It is shown that the fluctuations of charge and magnetic flux depend on not only the parameters of the circuit components but also the environmental temperature and squeezing parameters, while the fluctuations don't depend on displacement parameters. |
