Stochastic unraveling of time-local quantum master equations beyond the Lindblad class
Ulrich Kleinekathoefer, Ivan Kondov, Michael Schreiber
A new method for stochastic unraveling of general time-local quantum master equations (QME) which involve the reduced density operator at time t only is proposed. The present kind…
A density matrix approach to photoinduced electron injection
Michael Schreiber, Ivan Kondov, Ulrich Kleinekathoefer
Electron injection from an adsorbed molecule to the substrate (heterogeneous electron transfer) is studied. One reaction coordinate is used to model this process. The surface phono…
Exciton scattering in light-harvesting systems of purple bacteria
Pavel Herman, Ulrich Kleinekathoefer, Ivan Barvik +1
Using the reduced density matrix formalism the exciton scattering in light-harvesting systems of purple bacteria is calculated. The static disorder (fluctuations of the site energi…
Excitons in a Photosynthetic Light-Harvesting System: A Combined Molecular Dynamics/Quantum Chemistry and Polaron Model Study
Ana Damjanovic, Ioan Kosztin, Klaus Schulten
The dynamics of pigment-pigment and pigment-protein interactions in light-harvesting complexes is studied with a novel approach which combines molecular dynamics (MD) simulations w…
Perturbative treatment of intercenter coupling in Redfield theory
Ulrich Kleinekathoefer, Ivan Kondov, Michael Schreiber
The quantum dynamics of coupled subsystems connected to a thermal bath is studied. In some of the earlier work the effect of intercenter coupling on the dissipative part was neglec…
Efficiency of different numerical methods for solving Redfield equations
Ivan Kondov, Ulrich Kleinekathoefer, Michael Schreiber
The numerical efficiency of different schemes for solving the Liouville-von Neumann equation within multilevel Redfield theory has been studied. Among the tested algorithms are the…
