Waiting time distributions of electron transfers through quantum dot Aharonov-Bohm interferometers

Sven Welack, Shaul Mukamel, YiJing Yan

We present a statistical readout method for quantum interferences based on time series analysis of consecutive single electron transfers through a double quantum dot Aharonov-Bohm…

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…

Switching the current through molecular wires

Ulrich Kleinekathoefer, GuangQi Li, Sven Welack +1

The influence of Gaussian laser pulses on the transport through molecular wires is investigated within a tight-binding model for spinless electrons including correlation. Motivated…

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…
