Derivation of the Curie-Weiss law in dynamical mean-field theory

Abstract

We present an analytic derivation of the linear temperature dependence of the inverse static susceptibility (formula presented) near the transition from a paramagnetic-to-ferromagnetic correlated metal within the dynamical mean-field theory for the Hubbard model. The equations for the critical temperature and interaction strength of the transition are also determined. © 2002 The American Physical Society.
