Magnetic properties and spin kinetics in Kondo lattices [PDF]

Magnetic Resonance in Solids, 2015
We present a theoretical model to describe unusual properties of Kondo lattices. The influence of the Kondo effect on the static magnetic susceptibility and electron spin resonance (ESR) parameters is studied in a simple molecular field approximation ...

Effect of band filling in the Kondo lattice: A mean-field approach

, 1998
The usual Kondo-lattice, including an antiferromagnetic exchange interaction between nearest-neighboring localized spins, is treated here in a mean-field scheme that introduces two mean-field parameters: one associated with the local Kondo effect, and ...

Topological Kondo semimetals emulated in heterobilayer transition metal dichalcogenides

Physical Review Research
The moiré structure of AB-stacked MoTe_{2}/WSe_{2} represents a natural platform to realize Kondo lattice models due to the discrepancy of the bandwidth between the individual layers.

Kondo effects in small-bandgap carbon nanotube quantum dots

Beilstein Journal of Nanotechnology, 2020
We study the magnetoconductance of small-bandgap carbon nanotube quantum dots in the presence of spin–orbit coupling in the strong-correlations regime. A finite-U slave-boson mean-field approach is used to study many-body effects.

Anomalous Kondo-effect in Quantum Dot at non-zero bias

, 1999
We present measurements on the Kondo-effect in a small quantum dot connected strongly to one lead and weakly to the other. The conductance of the dot reveals an offset of the Kondo resonance at zero magnetic field.

Topological Majorana Two-Channel Kondo Effect [PDF]

Physical Review Letters, 2017
A one-dimensional time-reversal-invariant topological superconductor hosts a Majorana Kramers pair at each end, where time-reversal symmetry acts as a supersymmetry that flips local fermion parity. We examine the transport anomaly of such a superconductor, floating and tunnel-coupled to normal leads at its two ends.

Heterodimensional Kondo superlattices with strong anisotropy

Nature Communications
Localized magnetic moments in non-magnetic materials, by interacting with the itinerary electrons, can profoundly change the metallic properties, developing various correlated phenomena such as the Kondo effect, heavy fermion, and unconventional ...

Suppression of the Kondo Resistivity Minimum in Magnetic Topological Insulators

, 2013
Magnetically-doped topological insulators are intensely studied in the search for exotic phenomena such as the quantum anomalous Hall effect. The interplay of electronic and impurity degrees of freedom leads to the Kondo effect, an increase in the ...

A theoretical study of the cluster glass-Kondo-magnetic disordered alloys

, 2009
The physics of disordered alloys, such as typically the well known case of CeNi1-xCux alloys, showing an interplay among the Kondo effect, the spin glass state and a magnetic order, has been studied firstly within an average description like in the ...
