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,

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.

Junction of three off-critical quantum Ising chains and two-channel Kondo effect in a superconductor [PDF]
, 2016 We show that a junction of three off-critical quantum Ising chains can be regarded as a quantum spin chain realization of the two-channel spin-1/2 overscreened Kondo effect with two superconducting leads.

Underscreened Kondo effect in S=1 magnetic quantum dots: Exchange, anisotropy and temperature effects [PDF]
, 2012 We present a theoretical analysis of the effects of uniaxial magnetic anisotropy and contact-induced exchange field on the underscreened Kondo effect in S=1 magnetic quantum dots coupled to ferromagnetic leads.

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.
