What is Quantum Noise Reduction of Electrical Circuit Having a Time-dependent Parameter: Transient Behaviour and Damping about?

In a previous paper [Physica A 197 (1993) 364] it was shown that a quantized, time-dependent LC-circuit, is able to generate squeezing e ect, its amount being controlled by the ÿnal value of the inductance. In the present work we pursue further this topic studying the transient regime and its in uence upon the squeezing e ect. A damping in the time evolution of charge and current in the circuit is found, in spite of having no dissipative element in the system.
