Abstract

Recent developments in many-body quantum chaos show that a quantum system with strong incoherent interactions can still he described with the aid of mean quasiparticle occupation numbers as in Fermi liquid theory. Wt: use these ideas and the geometric chaoticity of angular momentum coupling to explain the predominance of ground states with zero spin and the maximum possible spin for a system of randomly interacting fermions in a rotationally invariant mean field tan analog of the Hund rule). We show that spin ordering coexists with the chaotic features of the ground-state wave functions. (C) 2001 MAIK "Nauka/Interperiodica".
