This approach admits a physically clear and transparent description of transport processes in dynamical mesoscopic systems promising basic elements of solid-state devices for quantum information processing. One of the key effects, the quantum pump effect, is considered in detail. In addition, the theory for a recently implemented new dynamical source - injecting electrons with time delay much larger than the electron coherenS-matrix theoryTransport theoryElectronic books.S-matrix theory.Transport theory.530.13/8Moskalets Michael V477309MiAaPQMiAaPQMiAaPQBOOK9910463733303321Scattering matrix approach to non-stationary quantum transport240206UNINA
