Some characteristics of first-order phase transformations

WebbA first-order transition does not require any change of symmetry (otherwise, there could be no critical point where a first-order transition turns into a smooth crossover), and thus does not need an order parameter. In such a case, you cannot use Landau's theory to describe a first-order transition.

Paul Ehrenfest classified phase transitions based on the behavior of the thermodynamic free energy as a function of other thermodynamic variables. Under this scheme, phase transitions were labeled by the lowest derivative of the free energy that is discontinuous at the transition. First-order phase transitions exhibit a discontinuity in the first derivative of the free energy with respect to some thermodynamic variable. The various solid/liquid/gas transitions are classified as first-o… Webb6 juni 2024 · In 1973, Halperin, Lubensky and Ma showed that the fluctuations of the gauge field actually drive the phase transition to become first-order.
