We extend Wegner’s exact solution for the 2D density of states at the lowest Landau level with a short–range disorder to the cases of a double–layer system and a superlattice. For the double–layer system, an analytical expression for the density of states, illustrating the interplay between the tunnel splitting of Landau levels and the disorder–induced broadening, is obtained. For the superlatt...

Acta Vet. Brno 1999, 68: 41-50. The main objective of this study was to analyse the relationship between the slope of the plasma lactate accumulation in response to exercise and working capacity in two ...
