Nonuniversal critical phenomena along the lambda line of4He

I. Specific heat in three dimensions
Article

Abstract

General relations between the critical specific heat above and below the lambda transition of4He are derived. The specific heat aboveTλ is calculated in three dimensions up to two-loop order. The relations can be used to determine the effective renormalized static couplings of modelF without integrating the renormalization-group flow equations. The effect of different normalizations of the couplings is discussed. The theory is applicable both to asymptotic universal and to nonasymptotic nonuniversal properties well away fromTλ(P) and provides part of the basis for quantitative predictions of other nonuniversal critical phenomena along the lambda line.
