Characteristic state function
The characteristic state function or Massieu's potential in statistical mechanics refers to a particular relationship between the partition function of an ensemble. In particular, if the partition function P satisfies : P = \exp(- \beta Q) \Leftrightarrow Q=-\frac{1}{\beta} \ln(P) or P = \exp(+ \beta Q) \Leftrightarrow Q=\frac{1}{\beta} \ln(P) in which Q is a thermodynamic quantity, then Q is known as the "characteristic state function" of the ensemble corresponding to "P". Beta refers to the thermodynamic beta.
