Усиление квантового переноса и квантовый храповик

Quantum transfer model with time dependent Hamiltonian and decoherence is considered. Application of the vibronic resonance with a transition and decoherence tuning makes it possible to enhance the quantum transfer and make it directional. Directionality of the transtion can be discussed as quantum ratchet. Application of this mechanism in quantum photosynthesis is discussed.
