Abstract :

In the last four decades the Harmonic Oscillator with Variable Frequency (HOVF) has drawn big attention as the principal model leading to squeezing states. We use algebraic methods to solve this problem for the first time in the Schrodinger picture. The solution is presented in a compact recursive form through general continuous fractions and enables calculate the final state of the system and the dynamics for any frequency function including such with jump discontinuities. In addition, we implement a numerical calculation of the solution and study the transition from a sudden change to adiabatic behavior between two frequencies.
