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.

Destruction of the Kondo effect by a local measurement [PDF]

, 2002
We show that the local spin measurement which decoheres the localized spin in a Kondo system, suppresses the Abrikosov-Suhl resonance and destroys the Kondo effect.

CePdAl - a Kondo lattice with partial frustration [PDF]

, 2016
Magnetic frustration, which is well-defined in insulating systems with localized magnetic moments, yields exotic ground states like spin ices, spin glasses, or spin liquids.

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 ...

Co-operative Kondo effect in the two-channel Kondo lattice [PDF]

Physical Review B, 1999
We discuss the possibility of a co-operative Kondo effect driven by channel interference in a Kondo lattice where local moments are coupled to a single Fermi sea via two orthogonal scattering channels. In this situation, the channel quantum number is not conserved.

Kondo interaction in FeTe and its potential role in the magnetic order

Nature Communications, 2023
Finding d-electron heavy fermion states has been an important topic as the diversity in d-electron materials can lead to many exotic Kondo effect-related phenomena or new states of matter such as correlation-driven topological Kondo insulator.

Doniach diagram for ordered, disordered and underscreened Kondo lattices [PDF]

, 2007
The Doniach's diagram has been originally proposed to describe the competition between the local Kondo effect and the intersite RKKY interactions in cerium compounds.

Exotic Kondo Effect from Magnetic Trimers [PDF]

Physical Review Letters, 2005
Motivated by the recent experiments of Jamneala {\em et al.} [T. Jamnaela {\em et al.}, Phys. Rev. Lett. {\bf 87}, 256804 (2001)], by combining {\em ab-initio} and renormalization group methods, we study the strongly correlated state of a Cr trimer deposited on gold. Internal orbital fluctuations of the trimer lead to huge increase of $T_K$ compared to
