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.
Andreev scattering and conductance enhancement in mesoscopic semiconductor-superconductor junctions
Niels Asger Mortensen, Antti-Pekka Jauho, Karsten Flensberg
An inherent difficulty in studying mesoscopic effects in semiconductor--superconductor hybrid structures is the large Schottky barrier which often forms at the interface. A large t…
Dephasing in semiconductor-superconductor structures by coupling to a voltage probe
Niels Asger Mortensen, Antti-Pekka Jauho, Karsten Flensberg
We study dephasing in semiconductor-superconductor structures caused by coupling to a voltage probe. We consider structures where the semiconductor consists of two scattering regio…
Contact resistance of quantum tubes
Niels Asger Mortensen, Kristinn Johnsen, Antti-Pekka Jauho +1
We consider the conductance of a quantum tube connected to a metallic contact. The number of angular momentum states that the tube can support depends on the strength of the radial…
Conductance enhancement in quantum point contact-semiconductor-superconductor devices
Niels Asger Mortensen, Antti-Pekka Jauho, Karsten Flensberg +1
We present numerical calculations of the conductance of an interface between a phase-coherent two-dimensional electron gas and a superconductor with a quantum point contact in the…
Quasienergy Spectroscopy of Excitons
Kristinn Johnsen, Antti-Pekka Jauho
We theoretically study nonlinear optics of excitons under intense THz irradiation. In particular, the linear near infrared absorption and resonantly enhanced nonlinear sideband gen…
Inelastic quantum transport in superlattices: success and failure of the Boltzmann equation
A. Wacker, A. -P. Jauho, S. Rott +3
Electrical transport in semiconductor superlattices is studied within a fully self-consistent quantum transport model based on nonequilibrium Green functions, including phonon and…
