Dernek, Mustafa; Ünal, Nuri

J. Math. Phys. 54, No. 9, 092102, 10 p. (2013).

Summary: In this study, first we construct the quasi-coherent states for a damped and forced harmonic oscillator and discuss the transition of the system from the damped oscillations to forced steady state oscillations. Second, we generalize the Caldirola-Kanai Hamiltonian into the new systems such as the frequency and the mass parameters are time dependent and discuss three examples of them.
