Current and Noise in a FM/quantum dot/FM System
F. M. Souza, J. C. Egues, A. P. Jauho
Using the Keldysh nonequilibrium technique we calculate current, noise and Fano factor in a ferromagnetic(FM)-quantum dot-ferromagnetic(FM) system with Coulomb interaction and spin…
Time-dependent transport in interacting mesoscopic systems
A. P. Jauho
We review recent applications of the nonequilibrium Green function technique to time-dependent transport in mesoscopic systems.
Current responsivity of semiconductor superlattice THz-photon detectors
Anatoly A. Ignatov, Antti-Pekka Jauho
The current responsivity of a semiconductor superlattice THz-photon detector is calculated using an equivalent circuit model which takes into account the finite matching efficiency…
Frictional Coulomb drag in strong magnetic fields
M. C. Bonsager, K. Flensberg, B. Y-K. Hu +1
A treatment of frictional Coulomb drag between two 2-dimensional electron layers in a strong perpendicular magnetic field, within the independent electron picture, is presented. As…
Theory of Coherent Time-dependent Transport in One-dimensional Multiband Semiconductor Superlattices
Jon Rotvig, Antti-Pekka Jauho, Henrik Smith
We present an analytical study of one-dimensional semiconductor superlattices in external electric fields, which may be time-dependent. A number of general results for the (quasi)e…
Magneto-Coulomb drag: interplay of electron--electron interactions and Landau quantization
M. C. Bonsager, K. Flensberg, B. Y. -K. Hu +1
We use the Kubo formalism to calculate the transresistivity for carriers in coupled quantum wells in a large perpendicular magnetic field . We find that is enh…
Linear response theory of Coulomb drag in coupled electron systems
Karsten Flensberg, Ben Yu-Kuang Hu, Antti-Pekka Jauho +1
We report a fully microscopic theory for transconductivity, or, equivalently, momentum transfer rate, of Coulomb coupled electron systems. We use the Kubo linear response formalism…
Time-dependent transport in interacting and non-interacting mesoscopic systems
Antti-Pekka Jauho, Ned S. Wingreen, Yigal Meir
We consider a mesoscopic region coupled to two leads under the influence of external time-dependent voltages. The time dependence is coupled to source and drain contacts, the gates…
Time-Dependent Transport through a Mesoscopic Structure
Ned S. Wingreen, Antti-Pekka Jauho, Yigal Meir
We present a general formulation of the nonlinear, time-dependent current through a small interacting region, where electron energies are changed by time-dependent voltages. An exa…
Coulomb drag between two-dimensional electron systems
Antti-Pekka Jauho, Henrik Smith
The Coulomb contribution to the temperature-dependent rate of momentum transfer, , between two electron systems in parallel layers is determined by setting up two coupled Bo…
