The filled (open) dots represent the boundary between paramagnetic metallic (PM) and paramagnetic insulating (PI) phases as determined by DMFT with the initial input given by the metallic (insulating) hybridization function.

Insets to Fig. 8. In a disordered system the LDOS depends on a particular realization of the disorder in the system. To obtain a full understanding of the effects of disorder it would therefore in principle be necessary to determine the entire probability distribution function of the LDOS, which is almost never possible. Instead one might try to calculate moments of the LDOS. 83 It was already pointed out by Anderson42 that the “typical” values of random quantities, which are mathematically given by the most probable values of the probability distribution functions, should be used to describe localization.

Schematic plots explaining the filling dependence of Tc for interacting electrons with strong binary alloy disorder. Curves represent Tcp , the Curie temperature for the pure system, as a function of filling n at two different interactions U1 U2 . Left: For n < x, Tc of the disordered system can be obtained by transforming the open (for U 1 ) and the filled (for U2 ) point from n to neff = n/x, and then multiplying Tcp (n/x) by x as indicated by arrows.
