利用Hellmann-Feynman定理研究无耗散介观电感耦合电路中的能量涨落

摘要

Based on the quantization of the nondissipative mesoscopic inductance coupled circuits,the energy fluctuations of the systems are investigated with the generalized Hellmann-Feynman theorem.The results show that the energy fluctuations not only depend on the temperature,but the compents of the rncircuits.%在对无耗散介观电感耦合电路进行量子化的基础上,利用广义Hellmann-Feynman定理对电路中的能量涨落进行研究.结果显示能量涨落的大小不但与温度有关,而且还与组成电路的元件有关.
