Low-temperature transport through a quantum dot: The Anderson model out of equilibrium.
TLDR
The infinite-U Anderson model is applied to non-equilibrium transport through a quantum dot containing two spin levels weakly coupled to two leads, leading to an observable peak in the differential conductance when the non-Equilibrium bias equals the Zeeman energy.Abstract:
The infinite-U Anderson model is applied to nonequilibrium transport through a quantum dot containing two spin levels weakly coupled to two leads. At low temperatures, the Kondo peak in the equilibrium density of states is split upon the application of a voltage bias. The split peaks, one at the chemical potential of each lead, are suppressed by nonequilibrium dissipation. In a magnetic field, the Kondo peaks shift away from the chemical potentials by the Zeeman energy, leading to an observable peak in the differential conductance when the nonequilibrium bias equals the Zeeman energy.read more

TL;DR: Meir et al. as mentioned in this paper reported measurements on a new generation of SETs that display all the aspects of the Kondo phenomenon: the spin singlet forms and causes an enhancement of the zero-bias conductance when the number of electrons on the artificial atom is odd but not when it is even.

A tunable kondo effect in quantum dots
TL;DR: A tunable Kondo effect has been realized in small quantum dots and measurements of the temperature and magnetic field dependence of a Coulomb-blockaded dot show good agreement with predictions of both equilibrium and nonequilibrium Kondo effects.

Kondo resonance in a single-molecule transistor
TL;DR: The Kondo resonance can be tuned reversibly using the gate voltage to alter the charge and spin state of the molecule and persists at temperatures up to 30 K and when the energy separation between the molecular state and the Fermi level of the metal exceeds 100 meV.
