Tight-binding study of interface states in semiconductor heterojunctions
A. V. Kolesnikov, R. Lipperheide, U. Wille
Localized interface states in abrupt semiconductor heterojunctions are studied within a tight-binding model. The intention is to provide a microscopic foundation for the results of…
Comment on ``Search for two-scale localization in disordered wires in a magnetic field''
A. V. Kolesnikov, K. B. Efetov
In a recent work Schomerus and Beenakker [Phys. Rev. Lett. 84, 3927 (2000)] tried to check numerically our prediction about a two-scale localization in disordered wires in a weak m…
Two-scale localization of wave functions in disordered wires in a weak magnetic field
A. V. Kolesnikov, K. B. Efetov
Using the supersymmetry technique combined with the transfer matrix method we calculate different physical quantities characterizing localization in disordered wires. In particular…
Two-scale localization in disordered wires in a magnetic field
A. V. Kolesnikov, K. B. Efetov
Calculating the density-density correlation function for disordered wires, we study localization properties of wave functions in a magnetic field. The supersymmetry technique combi…
Distribution of complex eigenvalues for symplectic ensembles of non-Hermitian matrices
A. V. Kolesnikov, K. B. Efetov
Symplectic ensemble of disordered non-Hermitian Hamiltonians is studied. Starting from a model with an imaginary magnetic field, we derive a proper supermatrix -model. The zero-…
Two-dimensional weakly interacting Fermi gas in a magnetic field: Level splitting
Alexei Kolesnikov
We apply the diagram-technique formalism beyond the Hartree-Fock approximation to a two-dimensional nearly ideal electron gas in a weak perpendicular magnetic field. The case of an…
