Abstract
Classical chaotic dynamics has moved into yet another field. According to Ragnar Fleischmann, Theo Geisel and Roland Ketzmerick of Frankfurt University, Germany, the mathematical framework used to characterise chaotic dynamics can be applied to electron transport experiments in two-dimensional electron gases (2DEGs) that have been modulated by a periodic lattice of strong scatterers (Phys. Rev. Lett (1992) 68 1367). They have shown that chaos and nonlinear resonances are clearly reflected in the magnetotransport in lateral surface superlattices and from this they offer an explanation for a series of peculiar magnetoresistance peaks observed recently in “antidot arrays” on semiconductor heterojunctions.
