Harmonic oscillator with time - dependent mass and frequency

Creators

Description

A general treatment of the quantal harmonic oscillator with time-dependent mass and frequency is presented. The treatment is based on the use of some time-dependent transformations in the method of invariants of Lewis and Riesenfeld. Exact coherent states for such a system are also constructed. (A.C.A.S.)
