Effect of Substitutional Impurities on the Electronic States and Conductivity of Crystals with Half-filled Band
E. P. Nakhmedov, H. Feldmann, R. Oppermann +1
Low temperature quantum corrections to the density of states (DOS) and the conductivity are examined for a two-dimensional(2D) square crystal with substitutional impurities. By sum…

Distribution function of the local density of states of a one-channel weakly disordered ring in an external magnetic field
H. Feldmann, E. P. Nakhmedov, R. Oppermann
A real space diagrammatic method, which is an extension of the Berezinskii technique to problems with periodic boundary condition, is formulated to study the density of states (DOS…

Spin - glass transition in Kondo lattice with quenched disorder
M. N. Kiselev, R. Oppermann
We use the Popov-Fedotov representation of spin operators to construct an effective action for a Kondo lattice model with quenched disorder at finite temperatures. We study the com…
