Exact Stochastic Unraveling of an Optical Coherence Dynamics by Cumulant Expansion
Jan Olsina, Tobias Kramer, Christoph Kreisbeck +1
A numerically exact Monte Carlo scheme for calculation of open quantum system dynamics is proposed and implemented. The method consists of a Monte-Carlo summation of a perturbation…
Absorption Spectra of Astaxanthin Aggregates
Jan Olsina, Milan Durchan, Babak Minofar +2
Carotenoids in hydrated polar solvents form aggregates characterized by dramatic changes in their absorption spectra with respect to monomers. Here we analyze absorption spectra of…
Parametric Projection Operator Technique for Second Order Non-linear Response
Jan Olsina, Tomas Mancal
We demonstrate the application of the recently introduced parametric projector operator technique to a calculation of the second order non-linear optical response of a multilevel m…
Electronic Coherence Dephasing in Excitonic Molecular Complexes: Role of Markov and Secular Approximations
Jan Olsina, Tomas Mancal
We compare four different types of equations of motion for reduced density matrix of a system of molecular excitons interacting with thermodynamic bath. All four equations are of s…
