Energy dissipation of electron solitons in a quantum well

2006 Physical Review B  
A linear response theory is provided for the dynamic interaction effects of an electron soliton confined in semiconductor quantum well with a conducting surface or a two-dimensional electron gas. It is shown that the soliton-electron-gas effective potential contains a dissipative component resisting against changes of the soliton charge density. Due to the energy dissipation moving solitons are stopped and the nonstationary excitations of the wave packet relax to the standing ground state.
