Kondo Effect in Artificial and Real Molecules
In this Thesis we develop a novel direction in the theory of nano-objects, i.e., structures of nanometer size in a tunnel contact with macroscopic electron reservoirs (metallic leads). This theory arose and was developed rapidly during the two recent decades as a response to challenging achievements of modern nanotechnology and experimental techniques. Evolution of this technology enabled the f...
متن کاملMott transition and Kondo screening in f-electron metals.
We study how a finite hybridization between a narrow correlated band and a wide conduction band affects the Mott transition. At zero temperature, the hybridization is found to be a relevant perturbation, so that the Mott transition is suppressed by Kondo screening. In contrast, a first-order transition remains at finite temperature, separating a local-moment phase and a Kondo-screened phase. Th...
متن کاملDistribution of the Kondo Temperature in Mesoscopic Disordered Metals
A local magnetic impurity is known to change the ground state of a Fermi liquid due to correlations created by the exchange interaction between its localised spin and the delocalised electrons. As a result, the magnetic impurity spin is screened at zero temperature by the formation of the Kondo singlet with the conduction electrons. Disorder is affecting the formation of the Kondo singlet in va...
متن کاملHexadecapolar Kondo effect in URu2Si2?
We derive the coupling of a localized hexadecapolar mode to conduction electrons in tetragonal symmetry. The derivation can be easily adapted to arbitrary multipoles in an arbitrary environment. We relate our model to the two-channel Kondo (2CK) model and show that for an f(2) configuration a relevant crystal field splitting in addition to the 2CK interaction is intrinsic to tetragonal symmetry...
متن کاملHOW THE KONDO EFFECT CAN EXIST IN Gd INTERMETALLIC COMPOUNDS
Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of Kondo Lattice. We suggest that the conduction electrons have gained local character. It is shown that Kondo effect should be observed...
