The nonlinear conductance of semiconductor heterostructures and single molecule devices
exhibiting Kondo physics has recently attracted attention. We address the observed sample …

Electron tunneling through a double quantum-dot molecule side attached to a quantum wire,
in the Kondo regime, is studied. The mean-field finite-U slave-boson formalism is used to …

The low-temperature transport properties of a molecule are studied in the field-effect
transitor geometry. The molecule has an internal mechanical mode that modulates its …

The conductance through a molecular device including electron-electron and electron-
phonon interactions is calculated using the numerical renormalization group method. At low …

The transport properties of nanostructured systems are deeply affected by the geometry of

Transport through molecular magnets is studied in the regime of strong coupling to the
leads. We consider a resonant-tunneling model where the electron spin in a quantum dot or …

We investigate theoretically the nonequilibrium transport properties of carbon nanotube
quantum dots. Owing to the two-dimensional band structure of graphene, a double orbital …

Condensed matter systems containing transition metals, be it single molecules or crystalline
solids, exhibit many complex physical phenomena that warrant the constant interest of the …
