Computer simulation can provide valuable insight into the forces driving biomolecular liquid–liquid phase separation. However, simulated systems have a limited size, which makes it important to minimize and control finite-size effects. Here, using phenomenological free-energy ansatz, we investigate how single-phase densities observed in canonical system under coexistence conditions depend on si...

Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization,  internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.

The symmetry properties, order parameters, and magnetoelectric phase diagrams of multiferroics are discussed. After brief reviews of Ni3V2O8, TbMnO3, and RbFe(MoO4)2, we present a detailed analysis of RMn2O5 (with R=Y, Ho, Dy, Er, Tb, Tm). PACS numbers: 75.25.+z,75.10.Jm,75.40.Gb Submitted to: J. Phys.: Condens. Matter Order Parameters and Phase Diagrams of Multiferroics 2

This study was aimed at using the solid–liquid phase diagrams for three binary mixtures of saturated fatty acids, especially the phase transitions below the liquidus line. These mixtures are compounded by caprylic acid (C8:0) + myristic acid (C14:0), capric acid (C10:0) + palmitic acid (C16:0), lauric acid (C12:0) + stearic acid (C18:0), differing by six carbon atoms between carbon chains. The ...

The stability hierarchy between different phases of a chemical compound can be accurately reproduced in a topological phase diagram. This type of phase diagrams may appear to be the result of simple extrapolations, however, experimental complications quickly increase in the case of crystalline trimorphism (and higher order polymorphism). To ensure the accurate positioning of stable phase domain...
