    • Exponential tails in the DOS prohibit the formation of a genuine disorder and/or correlation induced gap in the spectrum. However, a "soft gap," where the spectrum vanishes at a single point, is permitted.

    • Equation (4) can be derived within Hartree-Fock theory. We find it to be valid even at strong interactions.

    • The same holds true when n = 1 = x, i.e., when the upper alloy subband is half filled.

    • We are currently investigations this transition scenario at T = 0 using the the numerical renormalization group. [K. Byczuk, W. Hofstetter, and D. Vollhardt (unpublished)].
