Abstract
The quantum dynamics of the photodetached electron of H(-) in electric field near a surface are studied in the time domain. The evolution of wave packet for different manifold eigenstates with limited lifetimes is obtain analytically. It is found that the quantum coherence and temporal evolution of surface electronic wave packet can be controlled by the laser central energy and electric field. The correspondence between classical and quantum mechanics is shown explicitly in the system. Numerical simulation shows that the temporal evolution of photodetached electronic wave packet on elastic surface exhibits some similar properties of time-resolved two-photon photoemission signal of surface electron.
