Tricritical and Critical End-Point Phenomena under Random Bonds
Physical Review Letters, 1996The effect of bond randomness on tricritical and critical end-point phenomena is studied by renormalization-group theory. In three dimensions, the pure-system tricritical point is replaced by a line segment of second-order transitions dominated by randomness and bounded by a multicritical point and a random-bond tricritical point, which reaches zero ...

Classical behavior of the critical end point
Ferroelectrics, 1988Abstract The three-dimensional phase diagram in the vicinity of the critical end point has been calculated using the universal unfolding of the batterfly potential. Contour representations of the order parameter and responses have been also given.

Noncritical interface near a critical end point II
Physica A: Statistical Mechanics and its Applications, 1980Abstract The tension of the interface between a noncritical phase α and a near-critical phase βγ, or between α and the individual β and γ phases into which βγ separates, is discussed. A thermodynamic description of a critical end point is given, earlier theoretical results on the interfacial tensions are reviewed, and the earlier theory is ...

Noncritical interface near a critical end point
The Journal of Chemical Physics, 1977The interface between a noncritical phase and a critical or near-critical phase is studied. Its structure and tension are deduced from the van der Waals, Cahn–Hilliard theory with a model free-energy density. The composition profile is found to be such that the composition in the interface approaches that of the noncritical phase on the one side ...

THE CHIRAL SUSCEPTIBILITY AROUND THE CRITICAL END POINT
Modern Physics Letters A, 2013This paper is devoted to locate the position of critical end point (CEP) and study its properties. The CEP for different current quark masses are located. It is found that as the current quark mass tends to zero, the position of the CEP tends to the tricrtical point (TCP), while the height of the chiral susceptibility tends to infinity faster and ...

The surface tension of non-critical interfaces near critical end points
Molecular Physics, 1984We have calculated the surface tension σ of the non-critical interfaces which occur near the critical end point for liquid-liquid phase separation. Our calculations are based on a non-local, two-density, mean field approximation to the free energy functional.

Phase boundaries near critical end points. I. Thermodynamics and universality
Physical Review B, 1991The vicinity of a critical end point is analyzed in order to reveal singularities arising in the form of the first-order phase boundary to the noncritical phase. Phenomenological arguments are presented and critically assessed that directly relate the nonanalytic behavior of the phase boundary to universal features of the bulk thermodynamics on the ...

Critical end point behaviour near and away from a tricritical point
Physica A: Statistical Mechanics and its Applications, 1987Measurements are reported of the intensity and the angular dissymmetry of light scattered from 'quasi-binary' and binary mixtures of ethane and heavier hydrocarbons, that have varying widths of the three-phase region $(\Delta T)$. The critical exponents $\gamma$ and $\nu$ are estimated by approaching the Lower Critical End Points (LCEP) from the two ...
