We present a simple approach to calculate the thermodynamic properties of single Kondo impurities including orbital degeneracy and crystal field effects (CFE) by extending a previous proposal by Schotte and Schotte (1975 Phys. Lett. 55A 38). Comparison with exact solutions for the specific heat of a quartet ground state split into two doublets shows deviations below 10% in the absence of CFE and a quantitative agreement for moderate or large CFE. As an application, we fit the measured specific… 

ARPES view on surface and bulk hybridization phenomena in the antiferromagnetic Kondo lattice CeRh2Si2

An angle-resolved photoemission spectroscopy study of the Kondo lattice antiferromagnet CeRh2Si2, where the surface and bulk Ce-4f spectral responses were clearly resolved and a fine structure near the Fermi edge reflecting the crystal electric field splitting of the bulk magnetic 4f 15/2 state is revealed.

Dual nature of electron spin resonance in YbCo2Zn20 intermetallic compound

In single crystals of YbCo2Zn20 intermetallic compound, two coexisting types of electron spin resonance signals related to the localized magnetic moments of cobalt and to itinerant electrons have

Learning crystal field parameters using convolutional neural networks

A deep machine learning algorithm that employs a two-dimensional convolutional neural network that is trained on magnetization, magnetic susceptibility and specific heat data that is calculated theoretically within the single-ion approximation and further processed using a standard wavelet transformation is presented.

Tuning the Kondo effect in Yb(Fe$_{1-x}$Co$_{x}$)$_{2}$Zn$_{20}$

We study the evolution of the Kondo effect in heavy fermion compounds, Yb(Fe$_{1-x}$Co$_{x}$)$_{2}$Zn$_{20}$ (0$\leqslant$ x $\leqslant$ 1), by means of temperature-dependent electric resistivity and



Ordering temperature and thermodynamic properties of Kondo systems

We consider a system of Kondo impurities with an RKKY interaction J between them. Using the exact solution of the impurity and approximating the effect of J, we calculate the critical temperature Tc

Crystal-field effects in the mixed-valence compounds Yb2M3Ga9 (M= Rh, Ir)

Magnetic susceptibility, heat capacity, and electrical resistivity measurements have been carried out on single crystals of the intermediate valence compounds Yb2 Rh3 Ga9 and Yb2 Ir3 Ga9. These

A “fermi-liquid” description of the Kondo problem at low temperatures

We take as granted Anderson's statement that in the low-temperature limit the usual Kondos-d model evolves toward a fixed point in which the effective exchange coupling of the impurity with the

Thermopower of an SU(4) Kondo resonance under an SU(2) symmetry-breaking field

We calculate the thermopower of a quantum dot described by two doublets hybridized with two degenerate bands of two conducting leads, conserving orbital (band) and spin quantum numbers, as a function

We calculate the finite temperature and non-equilibrium electric current through systems described generically at low energy by a singlet and two spin doublets for N and N ± 1 electrons respectively,

The splitting of the Kondo resonance in the density of states of an Anderson impurity in a finite magnetic field is calculated from the exact Bethe-ansatz solution. The result gives an estimate of

Magnetic-field probing of an SU(4) Kondo resonance in a single-atom transistor.

This work claims that the SU(2) symmetric case corresponds to a pure valley Kondo effect of fully polarized electrons and demonstrates experimentally a symmetry crossover from an SU(4) ground state to apure orbital SU( 2) groundState as a function of magnetic field.
