Vv. Dodonov et al., SQUEEZING FOR THE ONE-MODE ELECTROMAGNETIC-FIELD OSCILLATOR WITH DELTA-KICKED FREQUENCY, Nuovo cimento della Societa italiana di fisica. B, Relativity, classical and statistical physics, 109(10), 1994, pp. 1023-1037
Squeezing phenomenon is analysed for the non-stationary forced harmoni
c oscillator which is perturbed parametrically by very short pulses. T
he energy of the oscillator, distribution function and the squeezing c
oefficients as well as some other values are calculated for the models
of and pulses, rectangular steps and some others types of time-depend
ence of the frequency of the oscillator.
