Analytical Perturbed Hard Sphere Models Based on Solubility and Volumetric Studies of Organic Solids Interacting With Supercritical Fluids
… benefit enormously the modelling of the supercritical phase. An expression was derived that indicates the solubility data or gas chromatography data are not well suited for obtaining v(,2); therefore, a new experimental technique was designed. The solubility data were well correlated by …

Chiral symmetry restoration in the three-dimensional four-fermion model at non-zero temperature and density
… in Quantum Chromodynamics. It is shown that the critical properties near the finite temperature and zero density transition with a large number of fermion species N in the system can be described by mean field theory. It is also shown both analytically and numerically that the width of the region …
