| Dec 4, 2013 at 18:26 | comment | added | Sergej Moroz | In general, the order of the phase transition tells us how bad the non-analyticity of the thermodynamics potential is at the phase transition point. The third order phase transition has a discontinuity in the third derivative of the thermodynamic potential, while the first and the second derivatives are continuous. | |
