Interference effects in the counting statistics of electron transfers through a double quantum dot
Sven Welack, Massimiliano Esposito, Upendra Harbola +1
We investigate the effect of quantum interferences and Coulomb interaction on the counting statistics of electrons crossing a double quantum dot in a parallel geometry using a gene…
Coherent destruction of the current through molecular wires using short laser pulses
Ulrich Kleinekathoefer, GuangQi Li, Sven Welack +1
A molecular wire coupled to two electron reservoirs is investigated within a tight-binding approach including spin and Coulomb interaction. Under the assumption of weak coupling to…
Optimal control of molecular electronics by femtosecond laser pulses
GuangQi Li, Sven Welack, Michael Schreiber +1
Combining the features of molecular wires and femtosecond laser pulses gives the unique opportunity to optically switch electron currents in molecular devices with very high speed.…
The influence of ultra-fast laser pulses on electron transfer in molecular wires studied by a non-Markovian density matrix approach
Sven Welack, Michael Schreiber, Ulrich Kleinekathoefer
New features of molecular wires can be observed when they are irradiated by laser fields. These effects can be achieved by periodically oscillating fields but also by short laser p…
Transverse Spin-Orbit Force in the Spin Hall Effect in Ballistic Semiconductor Wires
Branislav K. Nikolic, Liviu P. Zarbo, Sven Welack
We introduce the spin and momentum dependent {\em force operator} which is defined by the Hamiltonian of a {\em clean} semiconductor quantum wire with homogeneous Rashba spin-orbit…
