In this work, we present a theory to calculate the time-dependent current flowing through an
arbitrary noninteracting nanoscale phase-coherent device connected to arbitrary …

A generalization of the Landauer-Büttiker picture of transport applicable to time-dependent
problems in the presence of dissipation is presented. Starting from the Schrödinger equation …

A theory of noise characteristics of a double-barrier resonant-tunneling system is
established. The noise-current power density has a Lorentzian form with a characteristic …

The Kondo effect in coupled quantum dots is investigated from the viewpoint of transmission
spectroscopy using the slave-boson formalism of the Anderson model. The …

We have used nonequilibrium quantum statistical mechanics to derive an exact expression
for the current and a rate equation for a simple model of a resonant tunneling diode …

Resonant tunneling through a quantum-box level is investigated in terms of nonequilibrium
Green's functions. A Hamiltonian with a Hubbard-type term, accounting for charging effects …

The equation of motion for nonequilibrium Green functions is derived within the framework of
the Schwinger and Keldysh formalism of perturbation expansion. For nonequilibrium …

The coherent transport through a coupled-quantum-dot system with strong intradot
interaction is investigated by the nonequilibrium Green's-functions method. The …

In this paper we present an approach to the dynamic transport properties of a double-barrier
resonant-tunneling system. Based on the nonequilibrium-Green's-function technique and …

The non-equilibrium Keldysh formalism is used to analyse the role of the electron-phonon
interaction in the transport properties of double-barrier heterostructures and micro-channels …
