Cyclotron Dynamics of a Kondo Singlet in a Spin-Orbit-Coupled Alkaline-Earth Atomic Gas

, 2014
We propose a scheme to investigate the interplay between Kondo-exchange interaction and quantum spin Hall effect with ultracold fermionic alkaline-earth atoms trapped in two-dimensional optical lattices using ultracold collision and laser-assisted ...

Kondo screening in Co adatoms with full Coulomb interaction

Physical Review Research, 2020
Using a numerically exact first-principles many-body approach, we revisit the “prototypical” Kondo case of a cobalt impurity on copper. Even though this is considered a well understood example of the Kondo effect, we reveal an unexpectedly strong ...

The Kondo Box: A Magnetic Impurity in an Ultrasmall Metallic Grain

, 1998
We study the Kondo effect generated by a single magnetic impurity embedded in an ultrasmall metallic grain, to be called a ``Kondo box''. We find that the Kondo resonance is strongly affected when the mean level spacing in the grain becomes larger than ...

Emergence of Kondo-assisted Néel order in a Kondo necklace model

Communications Materials
The interplay between Kondo screening and magnetic order has long been a central issue in the physics of strongly correlated systems. While the Kondo effect has traditionally been understood to suppress magnetism through the formation of local singlets ...

Additional energy scale in SmB6 at low-temperature

Nature Communications, 2016
Many discrepancies exist to question the nature of the candidate topological Kondo insulator, SmB6. Here, Jiao et al. observe in-gap states on well characterized (001) surfaces of SmB6, indicating a suppression of the Kondo effect at surface, which ...

Minimal realization of the Orbital Kondo effect in a Quantum Dot with two Leads

, 2007
We demonstrate theoretically how the Kondo effect may be observed in the transport of spinless electrons through a quantum dot. The role of conduction electron spin is played by a lead index.

Impact of Majorana fermions on the Kondo state in the carbon nanotube quantum dot

Journal of Physics Communications
We have studied the quantum conductance of the Kondo state in the carbon nanotube quantum dot (CNTQD) with side-attached multi-Majorana fermion states in topological superconductors (TSCs).

Spin-Valley Kondo Effect in Multi-electron Silicon Quantum Dots

, 2007
We study the spin-valley Kondo effect of a silicon quantum dot occupied by $% \mathcal{N}$ electrons, with $\mathcal{N}$ up to four. We show that the Kondo resonance appears in the $\mathcal{N}=1,2,3$ Coulomb blockade regimes, but not in the $\mathcal{N}=
