Hybridization of an s-wave impurity with graphene lattice

Communications in Physics
Hybridization function is a quantity characterizing electron hoppings between an impurity and a host material in which the impurity resides, a full understandinging of it is crucial for studying correlation effects in various impurity problems.

Weak ferromagnetism with the Kondo screening effect in the Kondo lattice systems

, 2013
We carefully consider the interplay between ferromagnetism and the Kondo screening effect in the conventional Kondo lattice systems at finite temperatures.

Orbital Kondo effect in carbon nanotubes

, 2005
Progress in the fabrication of nanometer-scale electronic devices is opening new opportunities to uncover the deepest aspects of the Kondo effect, one of the paradigmatic phenomena in the physics of strongly correlated electrons.

Interaction of spin and vibrations in transport through single-molecule magnets

Beilstein Journal of Nanotechnology, 2011
We study electron transport through a single-molecule magnet (SMM) and the interplay of its anisotropic spin with quantized vibrational distortions of the molecule.

Application of the S=1 underscreened Anderson lattice model to Kondo uranium and neptunium compounds

, 2010
Magnetic properties of uranium and neptunium compounds showing the coexistence of Kondo screening effect and ferromagnetic order are investigated within the Anderson lattice Hamiltonian with a two-fold degenerate $f$-level in each site, corresponding to $

Kondo Effect in Bosonic Spin Liquids [PDF]

Physical Review Letters, 2006
In a metal, a magnetic impurity is fully screened by the conduction electrons at low temperature. In contrast, impurity moments coupled to spin-1 bulk bosons, such as triplet excitations in paramagnets, are only partially screened, even at the bulk quantum critical point.

Blocking transport resonances via Kondo many-body entanglement in quantum dots

Nature Communications, 2016
The many-body Kondo effect manifests in low-temperature Coulomb blockaded quantum dots as a zero-bias conductance peak, which arises due to charge-fluctuation-driven transport.

Observing the universal screening of a Kondo impurity

Nature Communications, 2023
The Kondo effect, deriving from a local magnetic impurity mediating electron-electron interactions, constitutes a flourishing basis for understanding a large variety of intricate many-body problems. Its experimental implementation in tunable circuits has

Theory of Charge Kondo Effect on Pair Hopping Mechanism

, 2012
A new microscopic model of the charge Kondo effect is proposed, and is studied on the basis of a numerical renormalization group calculations. It is shown that the charge Kondo effect is caused by a pair hopping interaction between the conduction band ...

Orbital Kondo-Effect From Tunneling Impurities [PDF]

International Journal of Modern Physics B, 1997
The article reviews recent results for the low energy physics of fast tunneling centers in metallic environments. For strong enough couplings to the environment these tunneling centers display an orbital Kondo effect and give rise to a non-Fermi-liquid behavior.
