Time-dependent quantum transport in nanosystems: A nonequilibrium Green's function approach

MPSD Seminar
Quantum transport is often discussed in the steady-state regime where the characteristics of the system are described in terms of the energy-dependent transmission or conductance. There is, however, no guarantee that this description would capture the essential physics in, say, atomic-scale junction operating at high frequencies. Therefore, we look for an accurate theory for describing the full time-dependence. The time-dependence also provides us with ''transient spectroscopy'' which can give detailed information about the nanosystems out of equilibrium. [mehr]
