摘要：

Recent experimental observations of time-resolved multidimensional signals in the light-harvesting antennae Fenna-Mathews-Olson [G. S. Engel , Nature (London) 446, 782 (2007)] show large oscillations of exciton populations coupled to the long-lived coherences. These effects may not be reproduced by the standard Redfield theory which assumes weak coupling to a bath. A more general relaxation superoperator which holds for all system-bath coupling parameter regimes is constructed by taking into account the statistics (covariances) of Lindblad equation parameters. Simulations for a model dimer reproduce all observed strong coupling effects.
