	Phase transition - Wikipedia, the free encyclopedia
		The distinguishing characteristic of a phase transition is an abrupt sudden change in one or more physical properties, in particular the heat capacity, with a small change in a thermodynamic variable such as the temperature.
		The Ehrenfest scheme is an inaccurate method of classifying phase transitions, for it is based on the mean field theory of phases (to be described in a later section.) Mean field theory is inaccurate in the vicinity of phase transitions, as it neglects the role of thermodynamic fluctuations.
		Universality is a prediction of the renormalization group theory of phase transitions, which states that the thermodynamic properties of a system near a phase transition depend only on a small number of features, such as dimensionality and symmetry, and is insensitive to the underlying microscopic properties of the system.

	Self limiting microwave heaters - Patent 5410135
		A second order phase transition occurs at the melt temperature of the polymer.
		Near the thermal transition of the polymeric binder, where the thermal coefficient of expansion is large, huge thermal coefficients of conductivity are exhibited in near-percolation-threshold mixtures.
		The drop in conductivity is at least about 1.5 orders to about 2 orders of magnitude or higher as compared to the conductivity before the binder phase transition and in some instances at least about 5 to about 7 orders of magnitude, or higher, again, as compared to the conductivity before the binder phase transition.

		Going from water to ice is an example of a ``first order phase transition.'' Typically a first order phase transition is associated with a latent heat and a volume change; ice expands.
		Others have speculated that it is a second order phase transition but the problem is that no one has been able to find a thermodynamic quantity that diverges.
		The coefficient of the linear term is the linear compressibility; the coefficients of the nonlinear terms are the higher order compressibilities.

	The Ising model
		Since we are in uncharted territory where the simulation of phase transition in language is concerned, we will make as few assumptions as possible in the modeling process.
		As we have explained, a second-order phase transition is characterized by a smooth change from one state to another.
		A first-order phase transition is implemented by introducing two new features to the system that are mathematically simple.

		Recent results on high temperature phase transitions are described, and applications to electroweak baryogenesis are considered.
		We perform an analysis of the behaviour of the electroweak phase transition in the Minimal Supersymmetric Standard Model, in the presence of light stops.
		It has been recently shown that the observed baryon number may originate at the electroweak phase transition, provided that the Higgs boson and the lightest stop are sufficiently light.

	Absence of enhanced fluctuations as a first-order phase transition is approached: An exact transfer-matrix study (Site not responding. Last check: 2007-10-17)
		As a second-order phase transition is traversed critical scattering appears; these fluctuations serve notice of the impending loss of stability of the equilibrium phase.
		For a model first- order phase transition we rigorously prove, using exact thermodynamic quantities obtained from strip-transfer-matrix calculations, as well as finite-size-scaling analysis, that as a temperature-driven, symmetry- breaking, first-order phase transition is approached, no enhancement of fluctuations into the future product phase occurs.
		To be specific, we study the probability of occupation of the product phase (stable below the transition temperature), and demonstrate that this is a monotonically decreasing function as the transition temperature is approached from above.

	Exactly solvable heterophase fluctuations at a vibrational-entropy-driven first-order phase transition (Site not responding. Last check: 2007-10-17)
		The model employs anharmonic couplings between neighboring particles that cause the low-temperature phase to have a lower vibrational entropy (i.e., stiffer restoring forces) than the high- temperature phase.
		This entropy difference, as opposed to an internal energy difference, produces a sharp transition.
		In one dimension the model may be solved exactly using transfer-integral techniques, and the solutions show heterophase fluctuations connecting the parent and product phases only for temperatures very close to the transition.

		The study of the phase transition from first-order to second-order in the two dimensional Potts model due to random applied fields
		In this paper, we study the nature of phase transition of the two-dimensional six-state Potts model under the external random magnetic field.
		When the external random field is applied, the nature of phase can be altered from first-order to second-order.By employing the Monte Carlo simulation method, we inspected the energy histogram and Binder parameter of the six-state Potts model under the external random magnetic field.

	First-order phase transition and degenerate states (Site not responding. Last check: 2007-10-17)
		To simulate a first-order phase transition in an Ising model, we first implement, microscopically, a bias field where one of the spin states is energetically favoured over the other.
		We also implement degenerate states that are statistically favoured by constituents.
		Constituents will hold on to their low energy states up to a critical point at which sufficient energy will be in the system that, statistically, constituents will tend to be in a degenerate state.

		Thermodynamic limit of the first-order phase transition in the Kuramoto model
		In the Kuramoto model, a uniform distribution of the natural frequencies leads to a first-order (i.e., discontinuous) phase transition from incoherence to synchronization, at the critical coupling parameter $K_c$.
		For a finite population, we demonstrate that the population size $N$ may be included into a self-consistency equation relating $r$ and $K$ in the synchronized state.
