THE NAGAOKA STATE AND ITS STABILITY IN THE ONE-BAND HUBBARD-MODEL
Source PublicationPHYSICS LETTERS A
KeywordFerromagnetic State Theorem
AbstractIn this article, we discuss the stability of the Nagaoka state with an infinite number of holes in the infinite-U Hubbard model. We shall rigorously show that the Nagaoka state is stable if the total number of holes N(h) almost-equal-to N(LAMBDA)alpha with 0 less-than-or-equal-to alpha < 2/(d+2) as the number of lattice sites N(LAMBDA) tends to infinity. Our theorem improves greatly the previous results obtained by Barbieri et al. [Phys. Rev. B 41 (1990) 11697] and by Tian [Phys. Rev. B 44 (1991) 4444].
