TIME-DEPENDENT TRANSPORT IN QUANTUM WIRES

Prof. V. Gudmundsson (University of Iceland, Reykjavik)

I will show why an extension to the time-domain of the Lippmann-Schwinger (LS) scattering formalism for electron transport in a quantum wire with embedded subsystems has led us to consider an approach built on the generalized master equation (GME). We have been able to apply the GME-formalism to systems of considerable geometrical complexity, even in an external magnetic field. I shall demonstrate how familiar phenomena from the single-electron LS-formalism can be identified in the many-electron GME-approach, and discuss future interests.
