Energy transfer properties and absorption spectra of the FMO complex: from exact PIMC calculations to TCL master equations
Piet Schijven, Lothar Muehlbacher, Oliver Muelken
We investigate the excitonic energy transfer (EET) in the Fenna-Matthews-Olsen complex and obtain the linear absorption spectrum (at 300 K) by a phenomenological time-convolutionle…
Transient dynamics of the Anderson impurity model out of equilibrium
T. L. Schmidt, P. Werner, L. Muehlbacher +1
We discuss the transient effects in the Anderson impurity model that occur when two fermionic continua with finite bandwidths are instantaneously coupled to a central level. We pre…
Nonequilibrium many-body dynamics along a dissipative Hubbard chain: Symmetries and Quantum Monte Carlo simulations
Lothar Muehlbacher, Joachim Ankerhold
The nonequilibrium dynamics of correlated charge transfer along a one-dimensional chain in presence of a phonon environment is investigated within a dissipative Hubbard model. For…
Real-time Monte-Carlo simulations for dissipative tight-binding systems and time local master equations
Lothar Muehlbacher, Charlotte Escher, Joachim Ankerhold
The numerically exact path integral Monte Carlo approach for the real-time evolution of dissipative quantum systems (PIMC), particularly suited for systems with discrete configurat…
Electron transfer rates for asymmetric reactions
L. Muehlbacher, R. Egger
We use a numerically exact real-time path integral Monte Carlo scheme to compute electron transfer dynamics between two redox sites within a spin-boson approach. The case of asymme…
