Paper Abstract
Quantum wave dynamics in systems with potential wells, bathers and outer impenetrable walls has been studied using
solutions of time-dependent Schrodinger equation. Numerical integration of Schrodinger equation, calculation of dynamical
variables and its average values, Fourier-spectra were carried out for different initial conditions and different
relations between wave packet energy and bather height. In non-symmetric wells the oscillations of wave packets are
accompanied by multistep discrete tunneling of probability fluid from well through barrier. In double well potential
(symmetric wells) the temporal scales of oscillations and tunneling were investigated in details. Influence of additional
time-dependent potential on quantum wave packet dynamics in above listed systems is also discussed.
