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…
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.…
Stochastic unraveling of Redfield master equations and its application to electron transfer problems
Ivan Kondov, Ulrich Kleinekathoefer, Michael Schreiber
A method for stochastic unraveling of general time-local quantum master equations (QMEs) is proposed. The present kind of jump algorithm allows a numerically efficient treatment of…
Influence of Static and Dynamic Disorder on the Anisotropy of Emission in the Ring Antenna Subunits of Purple Bacteria Photosynthetic Systems
Pavel Herman, Ulrich Kleinekathoefer, Ivan Barvik +1
Using the reduced density matrix formalism the time dependence of the exciton scattering in light-harvesting ring systems of purple bacteria is calculated. In contrast to the work…
Photo-induced intermolecular charge transfer in porphyrin complexes
Michael Schreiber, Dmitry Kilin, Ulrich Kleinekathoefer
Optical excitation of the sequential supermolecule H_2P-ZnP-Q induces an electron transfer from the free-base porphyrin (H_2P) to the quinone (Q) via the zinc porphyrin (ZnP). This…
