    • note
    • A rather extreme limit of this phenomenon was considered in Ref. 8, where the authors studied the effect of fluctuations of the concentration of magnetic impurities exceeding the AG critical concentration nc, and therefore generating gapless regions optimal fluctuations surrounded by a gap-full matrix.

    • Notice that, in contrast with the case of Lifshits tails, in the present situation each optimal fluctuation contains typically a number N≫1 of quasiparticle states.
