Spin-Selective Kondo Insulator: Cooperation of Ferromagnetism and the Kondo Effect [PDF]
Physical Review Letters, 2012 We propose the notion of spin-selective Kondo insulator, which provides a fundamental mechanism to describe the ferromagnetic phase of the Kondo lattice model with antiferromagnetic coupling. This unveils a remarkable feature of the ferromagnetic metallic phase: the majority-spin conduction electrons show metallic- while the minority-spin electrons ...

From four- to two-channel Kondo effect in junctions of XY spin chains
Nuclear Physics B, 2016 We consider the Kondo effect in Y-junctions of anisotropic XY models in an applied magnetic field along the critical lines characterized by a gapless excitation spectrum.

Universal scaling of tunable Yu-Shiba-Rusinov states across the quantum phase transition
Communications Physics, 2023 Quantum magnetic impurities give rise to a wealth of phenomena attracting tremendous research interest in recent years. On a normal metal, magnetic impurities generate the correlation-driven Kondo effect.

Resolving the nonequilibrium Kondo singlet in energy- and position-space using quantum measurements
SciPost Physics, 2021 The Kondo effect, a hallmark of strong correlation physics, is characterized by the formation of an extended cloud of singlet states around magnetic impurities at low temperatures. While many implications of the Kondo cloud's existence have been verified,

The Kondo Effect in the Unitary Limit [PDF]
Science, 2000 We observe a strong Kondo effect in a semiconductor quantum dot when a small magnetic field is applied. The Coulomb blockade for electron tunneling is overcome completely by the Kondo effect, and the conductance reaches the unitary limit value. We compare the experimental Kondo temperature with the theoretical predictions for the spin-½ Anderson ...

Band Polarization Effect on the Kondo State in a Zigzag Silicene Nanoribbon
Nanomaterials, 2022 Using the Numerical Renormalization Group method, we study the properties of a quantum impurity coupled to a zigzag silicene nanoribbon (ZSNR) that is subjected to the action of a magnetic field applied in a generic direction.
