A tunable Kondo effect has been realized in small quantum dots. A dot can be switched from a Kondo system to a non-Kondo system as the number of electrons on the dot is changed from odd to even. The Kondo temperature can be tuned by means of a gate voltage as a single-particle energy state nears the Fermi energy. 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.

TLDR
A tunable two-impurity Kondo system in a strongly correlated carbon nanotube double quantum dot is investigated, accessing the full range of charge regimes, with good agreement with a numerical renormalization group study of the device.
Kondo resonance in a quantum dot molecule
We report a theoretical investigation of the Kondo effect in a quantum dot (QD) molecule, where a larger QD supports multiple transmission channels and a smaller side-coupled QD acts as the Kondo

Kondo effect in quantum dots and molecular devices
Kondo effect is a very important many-body phenomenon in condensed matter physics, which explains why the resistance increases as the temperature is lowered (usually <10 K) in dilute magnetic alloy,

We have observed the Kondo effect in strongly coupled semiconducting nanowire quantum dots. The devices are made from indium arsenide nanowires, grown by molecular beam epitaxy, and contacted by
Anomalous Kondo Effect in a Quantum Dot at Nonzero Bias
We present measurements on the Kondo effect in a small quantum dot connected strongly to one lead and weakly to the other. The conductance of the dot reveals an offset of the Kondo resonance at zero

Resonant tunneling through a two-level dot and double quantum dots
We study resonant tunneling through quantum-dot systems in the presence of strong Coulomb repulsion and coupling to the metallic leads. Motivated by recent experiments we concentrate on i) a single
Correlated electron transport through a quantum dot: The multiple-level effect.
TLDR
It is argued that characteristic peaks should be seen in differential conductance if the dot has a group of closely spaced levels, and these peaks provide a hallmark of Kondo-type correlation.
Kondo effect in a single-electron transistor
How localized electrons interact with delocalized electrons is a central question to many problems in sold-state physics. The simplest manifestation of this situation is the Kondo effect, which

TLDR
The current as a function of voltage for resonant tunneling through an Anderson impurity in the low-temperature, Kondo, regime is computed using perturbation theory in the Hubbard U repulsion.
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.

TLDR
Transport measurements are used to study the quantized energy levels in a small electron gas, referred to as a Coulomb island, and a decrease in the charging energy of the island is observed as the coupling to its leads is increased.
On the Electron Transport through a Quantum Dot
Electron transport through a quantum dot is discussed from the point of view of the Friedel sum rule. When an odd number of electrons are in the dot, the localized moment may be formed because of the
Size dependence of Kondo scattering in point contacts.
TLDR
By utilizing a mechanically controllable break junction, point contact spectra dV/dI were determined for various noble metals doped with magnetic impurities to find a significant enhancement of exchange coupling parameter 1, which leads to an enormous increase in the apparent Kondo temperature T& for small contact diameters.

TLDR
This work studies resonant tunneling through a single-level quantum dot in the presence of strong Coulomb repulsion beyond the perturbative regime and predicts that the sign of the zero-bias anomaly depends on the level position relative to the Fermi level of the leads.

A model for single-electron charging in semiconductor quantum dots that includes the standard Anderson on-site repulsion as well as the spin exchange that is inherently present among the electrons occupying the various quantum levels of the dot is analyzed.
