We present a real-time diagrammatic theory for transport through interacting quantum dots
tunnel coupled to normal and superconducting leads. Our formulation describes both the …

We consider charge transport through a nanoscopic object, eg, single molecules, short
nanotubes, or quantum dots, that is weakly coupled to metallic electrodes. We account for …

Steady-state observables, such as occupation numbers and currents, are crucial
experimental signatures in open quantum systems. The time-convolutionless (TCL) master …

The progress of experimental techniques at the nanoscale in the last decade made optical
measurements in current-carrying nanojunctions a reality, thus indicating the emergence of …

We study electron quantum transport through a strongly interacting Anderson quantum dot at
finite bias voltage and magnetic field at zero temperature using the real-time renormalization …

We investigate theoretically the transport properties of a closed Aharonov-Bohm
interferometer containing two quantum dots in the strong coupling regime. We find two …

We have measured the Kondo effect in a quantum ring connected to three terminals. In this
configuration nonlinear transport measurements allow us to check which lead contributes to …

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 …

The electron tunneling through a mesoscopic hybrid system, a normal-metal–quantum-dot–
superconductor (N− QD− S) system where the intradot Coulomb interaction is neglected, in …

We study relaxation dynamics in a strongly interacting two-site Fermi-Hubbard model that is
induced by coupling each site to a local fermionic bath. To derive the proper form of the …
