ABSTRACT: The time dependence of probability and Shannon entropy
of a modified damped harmonic oscillator is studied by using single and double Gaussian
wave functions through the Feynman path method. We establish that the damped coefficient as well as the
system frequency and the distance separating two consecutive waves of the initial
double Gaussian function influences the coherence of the system and can be used
to control its decoherence.
