Cotunneling current through quantum dots with phonon-assisted spin-flip processes
Jörg Lehmann, Daniel Loss
We consider cotunneling through a quantum dot in the presence of spin-flip processes induced by the coupling to acoustic phonons of the surrounding. An expression for the phonon-as…
Driven quantum transport on the nanoscale
Sigmund Kohler, Jörg Lehmann, Peter Hänggi
We explore the prospects to control by use of time-dependent fields quantum transport phenomena in nanoscale systems. In particular, we study for driven conductors the electron cur…
Vibrational effects in laser driven molecular wires
Jörg Lehmann, Sigmund Kohler, Volkhard May +1
The influence of an electron-vibrational coupling on the laser control of electron transport through a molecular wire that is attached to several electronic leads is investigated.…
Charge transport through a molecule driven by a high-frequency field
Sigmund Kohler, Sébastien Camalet, Michael Strass +3
We study the current and the associated noise for the transport through a two-site molecule driven by an external oscillating field. Within a high-frequency approximation, the time…
Resonant laser excitation of molecular wires
Sigmund Kohler, Jörg Lehmann, Sébastien Camalet +1
We investigate the influence of external laser excitations on the average current through bridged molecules. For the computation of the current, we use a numerically very efficient…
Rectification of laser-induced electronic transport through molecules
Jörg Lehmann, Sigmund Kohler, Peter Hänggi +1
We study the influence of laser radiation on the electron transport through a molecular wire weakly coupled to two leads. In the absence of a generalized parity symmetry, the molec…
