Abstract
Thermodynamic and electric properties of anisotropic compressible Hall stat es at higher Landau levels are studied using a mean field theory on the von Neumann lattice basis. It is shown that resistances agree with the recent experiments of anisotropic compressible states and the states have negative pressure. As implications, the collapse phenomena of the integer quantum H all effect are discussed. (C) 2001 Elsevier Science B.V. All rights reserve d.
