Exact Solutions for a Mode of the Electromagnetic Field in a Resonator with Time-Dependent Characteristics of the Internal Medium.

摘要

The problem of quantization of the electromagnetic field inside a resonator filled with a dielectric medium with time-dependent characteristics in the presence of the external alternating current is studied. The exact propagator, coherent and Fock's states are obtained for a separate quantized mode of the field represented by a quantum oscillator with time-dependent frequency linearly coupled via momentum with the external current. Delta-pulse excitation of the medium is considered as an example.
