Nonstationary and steady-state transport through a mesoscopic sample connected to particle reservoirs via time-dependent barriers is investigated by the reduced density operator method. The generalized master equation is solved via the Crank–Nicolson algorithm by taking into account the memory kernel which embodies the non-Markovian effects that are commonly disregarded. The lead–sample coupling takes into account the match between the energy of the incident electrons and the levels of the… 

Correlated time-dependent transport through a two-dimensional quantum structure

We use a generalized master equation (GME) to describe the nonequilibrium magnetotransport of interacting electrons through a broad finite quantum wire with an embedded ring structure. The finite

Generalized Master Equation Approach to Time-Dependent Many-Body Transport

It is shown that a generalized master equation written and solved in terms of many-body states provides the suitable formal framework to capture both the effects of the Coulomb interaction and electron–photon coupling due to a surrounding single-mode cavity.

Coexisting spin and Rabi oscillations at intermediate time regimes in electron transport through a photon cavity

This work theoretically model the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a far-infrared photon cavity and predicts that in the presence of a transverse magnetic field the interdot Rabi oscillations appearing in the intermediate and transient regime coexist with slower non-equilibrium fluctuations in the occupation of states for opposite spin orientation.

Backaction effects in cavity-coupled quantum conductors

We study the electronic transport through a pair of distant nanosystems ($S_a$ and $S_b$) embedded in a single-mode cavity. Each system is connected to source and drain particle reservoirs and the

It is verified that the stationary solution of the SOQREs is able to correctly describe the Kondo effect on a qualitative level, and a comparison with other methods, such as the second-order von Neumann approach and Hubbard-I approximation, is performed.



Transient regime in nonlinear transport through many-level quantum dots

We investigate the nonstationary electronic transport in noninteracting nanostructures driven by a finite bias and time-dependent signals applied at their contacts to the leads. The systems are

Time-dependent transport in interacting and noninteracting resonant-tunneling systems.

Analytical and numerical results for the exactly solvable noninteracting resonant-tunneling system are presented, and a connection to recent linear-response calculations, and to earlier studies of electron-phonon scattering effects in resonant tunneling is established.

Time-dependent quantum transport: A practical scheme using density functional theory

The implementation has been done assuming clamped ions and it is discussed how it can be extended to include dissipation due to electron-phonon coupling through the combined simulation of the electron-ion dynamics as well as electron-electron correlations.

An extended Keldysh formalism, well suited to properly take into account the initial correlations, is used in order to deal with the time-dependent current response of a resonant tunneling system. We
