Abstract

The problem of quantum harmonic oscillator with time-dependent frequency has been solved analytically only for special co(t) functions. In this paper (Sec. 1.) we give a recursive method to determine the creation and annihilation operators for any step-like 0)(0 (t) functions (i. e. functions being constant between jumps). In Sec. 2. we apply this method to jumps between two values of w. In Sec 3. we approximate more general functions with a series of small jumps, we examine the Fourier series of the function defined in Sec. 2, and show that even the first Fourier component leads to increasing squeezing.
