Abstract in another language

The capture of electrons moving in a quantum wire into an embedded quantum dot due to the interaction with optical phonons is studied on a quantum kinetic level within the density matrix approach. We find even at low temperatures where only phonon emission is possible a non-monotonic time-dependence of the bound state occupations due to virtual transitions. In the case of several bound dot states the capture in general results in a coherent superposition of these states.
