We study the interaction-driven localization transition, which a recent experiment (Richardella et al 2010 Science 327 665) in Ga1?xMnxAs has shown to come along with the multifractal behavior of the local density of states (LDoS) and the intriguing persistence of critical correlations close to the Fermi level. We show that the bulk of these phenomena can be understood within a Hartree?Fock (HF) treatment of disordered, Coulomb-interacting spinless fermions. A scaling analysis of the LDoS… CONTINUE READING
