Surface Kondo effect and non-trivial metallic state of the Kondo insulator YbB12 [PDF]

Nature Communications, 2016
Topological state in Kondo insulators has been provoked in SmB6, but the origin of surface states and topological order remain elusive. Here, Hagiwara et al.

Parity-independent Kondo effect of correlated electrons in electrostatically defined ZnO quantum dots [PDF]

Nature Communications
Quantum devices such as spin qubits have been extensively investigated in electrostatically confined quantum dots using high-quality semiconductor heterostructures like GaAs and Si.

Fractional shot noise of an SU(N) Kondo system [PDF]

Beilstein Journal of Nanotechnology
We consider transport through a multilevel interacting quantum dot (N-QD) in the Kondo regime. Using the Kotliar–Ruckentein slave boson approach (SBMFA) for an N-level Anderson model, we define effectively noninteracting quasiparticles of the SU(N) Kondo

Magnon damping as a probe of Kondo coupling in magnetically ordered systems [PDF]

Nature Communications
In d-electron systems, there can also be intricate interplay between Kondo coupling and magnetic interactions as that in f-electron systems, but the underlying mechanism remains elusive.

Valence skipping phenomena, charge Kondo effect, and superconductivity

AAPPS Bulletin, 2022
We review a recent progress of a superconductivity and a charge Kondo effect mediated by valence skippers which are elements skipping the valence state.

Dual Kondo effect charge ordering and zero thermal expansion in a correlated intermetallic

Communications Materials, 2022
Theoretical studies have predicted a Kondo effect driven charge density wave order with two sublattices characterized by different single-ion Kondo temperatures.

HOW THE KONDO EFFECT CAN EXIST IN Gd INTERMETALLIC COMPOUNDS [PDF]

Journal of Sciences, Islamic Republic of Iran, 2001
Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the ...

Kondo effect driven by chirality imbalance

Physical Review Research, 2020
We propose a novel mechanism of the Kondo effect driven by a chirality imbalance (or chiral chemical potential) of relativistic light fermions. This effect is realized by the mixing between a right- or left-handed fermion and a heavy impurity in the ...

Kondo QED: The Kondo effect and photon trapping in a two-impurity Anderson model ultrastrongly coupled to light

Physical Review Research, 2023
The Kondo effect is one of the most studied examples of strongly correlated quantum many-body physics. Another type of strongly correlated physics that has only recently been explored in detail (and become experimentally accessible) is that of ...

Kondo effect with Wilson fermions

, 2021
We investigate the Kondo effect with Wilson fermions. This is based on a mean-field approach for the chiral Gross-Neveu model including four-point interactions between a light Wilson fermion and a heavy fermion.
