WebAbstract. We have used the electromigration technique to fabricate a C 60 subscript C 60 \rm{C_{{60}}} roman_C start_POSTSUBSCRIPT 60 end_POSTSUBSCRIPT single-molecule transistor (SMT). We present a full experimental study as a function of temperature, down to 35 mK, and as a function of magnetic field up to 8 T in a SMT with odd number of … WebThe Kondo effect, the screening of the local magnetic moment by itinerant electrons, is a many-body quantum phenomenon which usually leads to a pronounced Kondo scattering at low temperatures [1]. The development of low dimensional systems offers a new opportunity to exploit the emergent aspects of the Kondo effect [2, 3].

This has been discussed for the …
WebIn post-stroke hemiparesis patients, the skeletal muscle mass decrease rapidly with the histological degradation. We investigated the effect of nutritional supplementation with whey protein and vitamin D on the muscle mass and muscle quality, in post-stroke convalescent rehabilitation patients in a randomized, single-blinded, placebo-controlled … Web24 Jul 1998 · In a quantum dot, the Kondo effect can be described as a narrow peak in the density of states (DOS) at the electrochemical potentials of the leads, μ L = μ R, as shown in Fig. 1 B (5–7). This Kondo resonance gives rise to enhanced conductance through the dot.
The Kondo effect can be considered as an example of asymptotic freedom, i.e. a situation where the coupling becomes non-perturbatively strong at low temperatures and low energies. In the Kondo problem, the coupling refers to the interaction between the localized magnetic impurities and the … See more In physics, the Kondo effect describes the scattering of conduction electrons in a metal due to magnetic impurities, resulting in a characteristic change i.e. a minimum in electrical resistivity with temperature.
