Thermodynamics
Thermodynamics is a physical science that studies the effects on material bodies, and on radiation in regions of space, of transfer of heat and of work done on or by the bodies or radiation...

Massieu function
In thermodynamics, Massieu function, symbol \Psi , is defined by the following relation: \Psi = \Psi \big \, where for every system with degree of freedom r one may choose r variables, e.g...

Free entropy
A thermodynamic free entropy is an entropic thermodynamic potential analogous to the free energy. Also known as a Massieu, Planck, or Massieu-Planck potentials , or free information. In statistical mechanics, free entropies frequently appear as the logarithm of a partition function...
