In contrast, the chemical potential of the IFG exhibits a nonmonotonic behavior: which starts rising quadratically with T above the Fermi energy instead of decreasing from it and returns to its usual monotonic decreasing behavior at temperatures that can be as large as twice the Fermi temperature (see Figure 1; see also Figure 1 in [60]).
In Figure 1(a) the temperature dependence of the ratio [mu]/[E.sub.F] is shown for different values of the ratio d/s and for N/V fixed, where [T.sub.F] denotes the Fermi temperature defined through the relation [E.sub.F] = [k.sub.B][T.sub.F], where [E.sub.F] is explicitly given by [(d/s[[bar.G].sub.d,s]).sup.s/d][(N/V).sup.s/d] in d dimensions.
The doping dependence of the gap [[DELTA].sub.0](x) is introduced through the Fermi temperature. To arrive to the normal state at T = 0 for each doping x an energy greater than [[DELTA].sub.0](x) or a depairing field [H.sub.c2](x) is required.
