28. In the case with n = 1. the chemical potential is restricted to the region min(Δ 0) < μ < min(Δ U). When we consider the MIT for n = 3, it is restricted to the parameter region max(Δ, 0) < μ < max(Δ, U). However, the MIT for n = 3 is easily obtained from that for n = 1 using the particle-hole transformation.
