...  The interaction is crucial for proper determination of the cyclotron braid structure because its short range part prevents the particles from approaching one an- other closer than the distance given by the density. ... See full document

... The quantum picture of the 2D DOS is in rather stark contrast to this, with a system that is localized at B 5 0, and at high-field consists of one, or a band of, extended states at the center of each Landau level ... See full document
