Abstract |
|
|
| We introduce a modified model for the problem of a damped harmonic oscillator in
presence of a driving force. The model is treated from the point of view of quantum
mechanics. The wave function in the Schršodinger picture is obtained. The connection
between the quasicoherent state and pseudostationary state is discussed. The constants
of motion are also introduced and the eigenfunctions and the corresponding eigenvalues
for pair of quadratic invariants are obtained. The phenomena of squeezing and the
Poissonian distribution are considered. It is shown that the system is sensitive to the
variation of the damping factor, °, as well as of the modulation factor, č. |
