In summary, we investigated the role of Coulomb interactions in the nature ofeigenfunction multifractality of an Anderson metal-insulator transition, basedon the Hartree-Fock approximation and the Ewald summation technique. As aresult, we showed that two types of mobility edges appear near the Fermi energyand at a high energy, respectively, where the low-energy mobility edge resultsfrom Coulomb interactions while the high-energy one is nothing but the mobilityedge of the Anderson localization transition without electron correlations.Indeed, not only multifractal scaling exponents but also the multifractalsingularity spectrum confirms the existence of two kinds of mobility edges:Their values differ from those of the Anderson metal-insulator transition andthe singularity spectrum collapses into two types of curves, implying two kindsof scale-invariance, which depends on the energy scale. We speculate that thisnovel nature of the eigenfunction multifractality would serve as valuableinformation for possible instabilities near a metal-insulator transition in thepresence of Coulomb interactions.
