摘要:

介观LC电路不可避免会处于辐射场中,把辐射场看成是由无穷多谐振子组成的,选择介观LC电路为研究对象。本文从介观LC电路与辐射场相互作用的哈密顿量出发,把辐射场看成库,通过对库求迹,推导了介观LC电路在辐射场作用下的密度方程。

Quantum LC circuit locates inevitably in radiation field; the thermal radiation field is a reservoir which is described by infinite harmonic oscillators, and quantum LC circuit is a system to be investigated. From the interaction between mesoscopic LC circuit and radiation field, the radiation is reservoir. We trace out the reservoir and deduce the equation of density.
