Spatially dependent Kondo effect in Quantum Corrals

, 2006
We study the Kondo screening of a single magnetic impurity inside a non-magnetic quantum corral located on the surface of a metallic host system. We show that the spatial structure of the corral's eigenmodes lead to a spatially dependent Kondo effect ...

Kondo screening in a Majorana metal

Nature Communications, 2023
Kondo impurities provide a nontrivial probe to unravel the character of the excitations of a quantum spin liquid. In the S = 1/2 Kitaev model on the honeycomb lattice, Kondo impurities embedded in the spin-liquid host can be screened by itinerant ...

Nonequilibrium Kondo effect by equilibrium numerical renormalization group method: The hybrid Anderson model subject to a finite spin bias

, 2018
We investigate Kondo correlations in a quantum dot with normal and superconducting electrodes, where a spin bias voltage is applied across the device and the local interaction $U$ is either attractive or repulsive.

Laser-irradiated Kondo insulators: Controlling the Kondo effect and topological phases [PDF]

Physical Review B, 2017
We theoretically investigate the nature of laser-irradiated Kondo insulators. Using Floquet theory and slave boson approach, we study a periodic Anderson model and derive an effective model which describes the laser-irradiated Kondo insulators. In this model, we find two generic effects induced by laser light.

Breakdown of the scaling relation of anomalous Hall effect in Kondo lattice ferromagnet USbTe

Nature Communications, 2023
The interaction between strong correlation and Berry curvature is an open territory of in the field of quantum materials. Here we report large anomalous Hall conductivity in a Kondo lattice ferromagnet USbTe which is dominated by intrinsic Berry ...

Kondo Effect of Quantum Dots in the Quantum Hall Regime

, 2003
Quantum dots in the quantum Hall regime can have pairs of single Slater determinant states that are degenerate in energy. We argue that these pairs of many body states may give rise to a Kondo effect which can be mapped into an ordinary Kondo effect in a

Low-carrier density and fragile magnetism in a Kondo lattice system [PDF]

, 2018
Kondo-based semimetals and semiconductors are of extensive current interest as a viable platform for strongly correlated states. It is thus important to understand the routes towards such dilute-carrier correlated states.

Tunable Kondo screening length at a Y-junction of three inhomogeneous spin chains

Nuclear Physics B, 2020
We derive the topological Kondo Hamiltonian describing a Y junction of three XX-spin chains connected to outer quantum Ising chains with different tilting angles for the Ising axis.

Tunable Kondo effect in a single donor atom

, 2009
The Kondo effect has been observed in a single gate-tunable atom. The measurement device consists of a single As dopant incorporated in a Silicon nanostructure. The atomic orbitals of the dopant are tunable by the gate electric field. When they are tuned

Kondo Effect in Dirac Systems [PDF]

Journal of the Physical Society of Japan, 2015
We investigate the Kondo effect in Dirac systems, where Dirac electrons interact with the localized spin via the s-d exchange coupling. The Dirac electron in solid state has the linear dispersion and is described typically by the Hamiltonian such as $H_k= v{\bf k}\cdot $ for the wave number ${\bf k}$ where $ _j$ are Pauli matrices.
