Thermodynamic potential: Difference between revisions

Revision as of 13:31, 19 November 2007

Thermodynamic potential ( $\Phi$ ). In the Landau theory of second order phase transitions the thermodynamic potential takes the form of a power series in the order parameter ( $\eta$ ) (Ref. 1 Eq. 143.1)

\left.\Phi (P,T,\eta )\right.=\Phi _{0}+\alpha (P,T)\eta +A(P,T)\eta ^{2}+C(P,T)\eta ^{3}+B(P,T)\eta ^{4}+...,

where P is the pressure and T is the temperature.
