激发相干态下介观电感耦合电路的量子效应
Quantum effects in inductance coupled mesoscopic circuit at excited coherent states
摘要
Abstract
Starting from the classical movement equation of a non-dissipative inductance coupled mesoscopic circuit, the circuit is quantized by using linear transformation method, and the quantum fluctuations of currents and charges at excited coherent states are calculated. The results show that the average and square average of current and charge of each loop are not zero without power, I.e., there exist quantum fluctuations. And the fluctuations are not only determined by the loop parameters, but also related to another loop's parameters and coupled inductance parameters. The quantum fluctuations in two circuits are relevant, and obviously depend on the state parameters of circuits, I.e., parameters of particle count states and coherent states.关键词
