摘要
通过正则变换和幺正变换的方法研究了有互感存在的情况下的介观电容耦合电路的量子涨落。结果表明当电路元件确定的时候,尤其是当L1/L2的值很小的时候,随着耦合程度的加深,一个回路的电荷的涨落很小,而另一个回路的电荷的涨落很大。
The quantum fluctuations of charges and currents of mesoscopic capacitance coupled circuit with mutual inductance are studied by using canonical transformation and unitary transformation. The results show that when the components of the circuit are given, especially when the value of L1 = L2 is very small, with the increasing of coupling extent, the quantum fluctuations of charges in one loop of circuit decrease obviously, while those charge of the other loop increase obviously.
