QUANTUM FLUCTUATIONS OF A DISSIPATIVE MESOSCOPIC CAPACITANCE RESISTANCE INDUCTANCE COUPLED CIRCUIT

摘要

Starting from Kirchhoff’s equation for each mesoscopic coupled circuit, we investigated the quantum fluctuations of a dissipative mesoscopic capacitance–resistance–inductance coupled circuit using canonical transformation and unitary transformation. It is shown that the quantum fluctuations of charges and currents are not only related to the pa- rameters of components in the self-circuit and coupled part, but also influenced by the parameters of other circuit. The uncertainty relations of the charges and currents are analyzed briefly.
