Curvilinear coordinates in the scaling theory of tricritical points

Research output: Contribution to journalArticlepeer-review

Abstract

We demonstrate the existence of homogeneity properties of the singular part of the free energy at the tricritical point of a soluble magneto-elastic model. The free energy is only homogeneous when viewed as a function of the appropriate curvilinear coordinates in the space of independent thermodynamic variables. It is not homogeneous as a function of the linear coordinates of either Griffiths of Riedel. The implications of this result for the general scaling theory of tricritical points are discussed.
