Phase transitions are introduced using the van der Waals gas as an example. The equations of state are derived from the Helmholtz free energy of the ideal gas. The behavior of this model is analyzed, and an instability leads to a liquid-gas phase transition. The Maxwell construction for the pressure at which a phase transition occurs is derived.

Induced phase transitions in ferroelectrics with diffuse phase transition
Physica Status Solidi (a), 1981Dielectric, thermal, electrocaloric, elastic, optical, and electromechanical properties of three ferroelectrics with diffuse phase transition (PLZT 8/65/35 ceramics, lead magnesium niobate and strontium barium niobate single crystals) are investigated in dependence on temperature and electric field strength.

Transition-when the cervix dilates from about 7 cm. to 10 cm.-is generally considered the most difficult phase of labor and it is at this time that the couple who have learned a psychoprophylactic technique, such as the Lamaze method, face their most stringent test. Control can be precarious.

Nomenclature of phase transitions
Quarterly Journal of the Royal Meteorological Society, 1958Discusses the curious situation in which the terminology of chemistry and physics has only five words to describe the six possible transitions between three states of matter.

Phase transitions denote transformations of the substance in one phase to another phase. The description of phase transitions is realized essentially within two schemes: a sharp interface across which the constitutive properties suffer a sudden change or a diffuse space region where the pertinent fields vary continuously. First, the jump conditions are

In Sect. 3.7 we have derived the equilibrium conditions for thermodynamic systems. Those considerations can be further generalized. In the form of a gedanken-experiment, we divided the total system into two fictitious partial systems and therewith created a simple non-equilibrium situation.

Overview of phases and phase transitions
Philosophical Magazine, 2015We provide an overview of some modern developments in the theory of phases and phase transitions in classical and quantum systems. We show the link between non-ergodicity and fidelity in quantum systems and discuss topological phase transitions. We show that the quantum phase transitions are associated with qualitative changes in some properties of the

This article considers phase transitions in matrix models that are invariant under a symmetry group as well as those that occur in some matrix ensembles with preferred basis, like the Anderson transition. It first reviews the results for the simplest model with a nontrivial set of phases, the one-matrix Hermitian model with polynomial potential.
