Concentration dependence of the transition temperature in metallic spin glasses
R. Serral Gracia, Th. M. Nieuwenhuizen, I. V. Lerner
The dependence of the transition temperature in terms of the concentration of magnetic impurities in spin glasses is explained on the basis of a screened RKKY interaction…
Deviations from the Gaussian distribution of mesoscopic conductance fluctuations
M. C. W. van Rossum, Igor V. Lerner, Boris L. Altshuler +1
The conductance distribution of metallic mesoscopic systems is considered. The variance of this distribution describes the universal conductance fluctuations, yielding a Gaussian d…
LEVEL CORRELATIONS DRIVEN BY WEAK LOCALIZATION IN 2-D SYSTEMS
Vladimir E. Kravtsov, Igor V. Lerner
We consider the two-level correlation function in two-dimensional disordered systems. In the non-ergodic diffusive regime, at energy ( is the Thouless energy), it…
SPECTRAL CORRELATIONS IN DISORDERED ELECTRONIC SYSTEMS: CROSSOVER FROM METAL TO INSULATOR REGIME
Arkady G. Aronov, Vladimir E. Kravtsov, Igor V. Lerner
We use the semiclassical approach combined with the scaling results for the diffusion coefficient to consider the two-level correlation function for a disordered e…
Universal Spectral Correlations at the Mobility Edge
V. E. Kravtsov, I. V. Lerner, B. L. Altshuler +1
We demonstrate the level statistics in the vicinity of the Anderson transition in dimensions to be universal and drastically different from both Wigner-Dyson in the metallic…
