【摘要】 通过量子化介观有源耗散电路,研究激发相干态和压缩真空态下介观电路的量子涨落及电源对量子涨落的影响,结果表明电路的电流及电压的涨落与外加电源无关,只与电路中的参数有关,是介观电路本身的量子特性。电路中电阻越大,电流的涨落越大,电压的涨落越小。更多还原

【Abstract】 The paper quantizes the circuit to investigate the fluctuation under excited coherent states and the effect of the driving source on the quantum fluctuation.The results show that the fluctuation of the charge and current in the circuit is the property of the circuit and that the parameter of the circuit affects the fluctuation,but the driving source has nothing to do with the fluctuations.更多还原
