Anisotropic magnetoconductivity of a three-dimensional disordered electron gas
(1989) [Journal article]The magnetoconductivity of a three-dimensional disordered electron gas is calculated from first principies with use of the exact electron eigenstates in a magnetic field, thus avoiding the usual semiclassical approximation ... -
Influence of fluctations on spin systems with spatially isotropic competing interactions
(1990) [Journal article]We consider spin systems with competing interactions isotropic with respect to the axes of a cubic lattice. A renormalization-group analysis carried to second order in E=d -4 demonstrates that the criticai behavior for the ...
