Single-Electron Approach for Time-Dependent Transport under External Noise
Prof. Shmuel Gurvitz
Weizmann Institute of Science, Israel

We develop a new approach to electron transport in time-dependent potentials, based on the single-electron Ansatz for the many-electron wave-function. This approach solves the time-dependent Schroedinger equation for a single electron, yields simple expressions for the transient currents for time-dependent potentials, and reproduces the Landauer formula for the steady state limit. In particular, the single-electron approach can be very effective for study the effects of fluctuating environment on transient and steady-state currents and charges in any mesoscopic system of coupled dots. Specific examples are presented.
