Repulsive step potential: a model for a liquid-liquid phase transition.
نویسندگان
چکیده
In the framework of the perturbation theory for fluids we study the model with the isotropic repulsive step potential which in addition to the hard core has a repulsive soft core of a larger radius. It is shown that this purely repulsive potential is sufficient to explain a liquid-liquid phase transition and liquid anomalies.

Investigation into the temperature dependence of isotropic- nematic phase transition of Gay- Berne liquid crystals
Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...
متن کاملLiquid-liquid phase transition for an attractive isotropic potential with wide repulsive range.
We investigate how the phase diagram of a repulsive soft-core attractive potential, with a liquid-liquid phase transition in addition to the standard gas-liquid phase transition, changes by varying the parameters of the potential. We extend our previous work on short soft-core ranges to the case of large soft-core ranges, by using an integral equation approach in the hypernetted-chain approxima...
متن کاملLiquid-Liquid Phase Transition and Glass Transition in a Monoatomic Model System
We review our recent study on the polyamorphism of the liquid and glass states in a monatomic system, a two-scale spherical-symmetric Jagla model with both attractive and repulsive interactions. This potential with a parametrization for which crystallization can be avoided and both the glass transition and the liquid-liquid phase transition are clearly separated, displays water-like anomalies a...
متن کاملPhase Transitions in Fluid State of Systems of Purely Repulsive Potentials
Phase behaviors in fluid state of systems of purely repulsive potentials (PRPs) are investigated with a recently proposed 3rd-order thermodynamic perturbation theory (TPT) (Phys. Rev. E. 2006, 74, 031119). It is found that a usual gas-liquid transition (GLT) always happen to several investigate PRPs, whose perturbation part as a function of particle separation holds a discontinuous point, or an...
متن کاملDisconnected glass-glass transitions and diffusion anomalies in a model with two repulsive length scales.
Building on mode-coupling-theory calculations, we report a novel scenario for multiple glass transitions in a purely repulsive spherical potential: the square shoulder. The liquid-glass transition lines exhibit both melting by cooling and melting by compression as well as associated diffusion anomalies, similar to the ones observed in water. Differently from all previously investigated models, ...
