Abstract

Abstract A free energy functional containing a critical n-vector field coupled to a non-critical scalar one, which commonly appears in the spin-phonon problem and near the ferromagnetic transition of the Hubbard model, is used within a field theoretical and renormalization group framework to obtain, to first order in ϵ=4− d, the universal scaling function of the equation of state near a fluctuation-induced tricritical point.
