Abstract
The capture of an electronic wave packet moving in a quantum wire into localized states of a quantum dot by means of LO phonon emission is studied on a quantum kinetic level. In general, if there is more than one bound state the capture process leads to the creation of a superposition of these states resulting in an oscillating wave packet inside the dot. It is shown that these oscillations can be efficiently controlled by means of the capture of a second wave packet moving towards the dot from the other side. Depending on the phase of the oscillations at the time of arrival of the second wave packet the amplitude of the spatial oscillations is either reduced or enhanced.
