Abstract: 

The dynamics of quantum wave packets in one-dimensional system with spatially confined quadratic potential, feedback and friction was numerically investigated in the context of the Schrodinger–Langevin–Kostin equation. The coherent oscillations are ¨ possible in the system under determined values of the feedback force and friction coefficient. There are the critical values of these quantities when the packet oscillations become complicated, the uncertainty product increases sharply, oscillates, but the Fourier-spectrum is everywhere dense.
