Green functions of electrons

The infinite system of differential equations for the nonequilibrium Green functions of electrons in a single-level quantum dot connected with two conducting leads is truncated by applying the mean-field approximation to the mean values of the products of four operators. As the result the system of Dyson equations for the two-point real-time nonequilibrium Green functions in the Keldysh formalism as well as that of the two-point imaginary-time Green functions are derived.

Plastocyanin (Pc) is a soluble copper protein that transfers electrons from cytochromeb6 fto photosystem I (PSI), two protein complexes that are localized in the thylakoid mem-branes in chloroplasts. The surface electrostatic potential distributionof Pc plays akey role in complex formationwith the membrane-bound partners. It is practically identical for Pcs fromplants and green algae, but is quite different for Pc fromferns.
