Nonperturbative Scaling Theory of Free Magnetic Moment Phases in Disordered Metals
A. Zhuravlev, I. Zharekeshev, E. Gorelov +3
The crossover between a free magnetic moment phase and a Kondo phase in low dimensional disordered metals with dilute magnetic impurities is studied. We perform a finite size scali…
Scaling of level statistics at the metal-insulator transition
I. Kh. Zharekeshev, B. Kramer
Using the Anderson model for disordered systems the fluctuations in electron spectra near the metal--insulator transition were numerically calculated for lattices of sizes up to 28…
Advanced Lanczos diagonalization for models of quantum disordered systems
Isa Kh. Zharekeshev, Bernhard Kramer
An application of an effective numerical algorithm for solving eigenvalue problems which arise in modelling electronic properties of quantum disordered systems is considered. We st…
Critical level statistics at the Anderson transition in four-dimensional disordered systems
I. Kh. Zharekeshev, B. Kramer
The level spacing distribution is numerically calculated at the disorder-induced metal--insulator transition for dimensionality d=4 by applying the Lanczos diagonalisation. The cri…
Phase diagram of localization in a magnetic field
T. Droese, M. Batsch, I. Kh. Zharekeshev +1
The phase diagram of localization is numerically calculated for a three-dimensional disordered system in the presence of a magnetic field using the Peierls substitution. The mobili…
Scaling of level-statistics and critical exponent of disordered two-dimensional symplectic systems
L. Schweitzer, I. Kh. Zharekeshev
The statistics of the energy eigenvalues at the metal-insulator-transition of a two-dimensional disordered system with spin-orbit interaction is investigated numerically. The criti…
