A quantum open system model of molecular battery charged by excitons
arXiv:1903.12140 · doi:10.1063/1.5096772
Abstract
The analytically tractable model employing Quantum Markovian Master Equations, derived by weak coupling procedure and satisfying complete positivity, is proposed to describe a model of molecular battery charged by a non-equilibrium excitonic reservoir. The excitons are produced by non-equilibrium processes involving, e.g. light absorption and chemical reactions. Various relations concerning the efficiency of the involved processes of energy transfer and the stability of battery are discussed. The model can be treated as an initial step in applications of mathematically sound version of Quantum Theory of Open Systems to complex processes of energy transfer in biological system and man-made devices based on organic materials.
