Unusual phase behavior of one-component systems with two-scale isotropic interactions

SV Buldyrev, G Malescio, CA Angell… - Journal of Physics …, 2009 - iopscience.iop.org
We study the phase behavior of systems of particles interacting through pair potentials with a
hard core plus a soft repulsive component. We consider several different forms of soft …

Hexatic phase and water-like anomalies in a two-dimensional fluid of particles with a weakly softened core

S Prestipino, F Saija, PV Giaquinta - The Journal of Chemical Physics, 2012 - pubs.aip.org
We study a two-dimensional fluid of particles interacting through a spherically symmetric and
marginally soft two-body repulsion. This model can exist in three different crystal phases …

We study the phase behavior of a classical system of particles interacting through a strictly
convex soft-repulsive potential which, at variance with the pairwise softened repulsions …

Hexatic phase and cluster crystals of two-dimensional GEM4 spheres

S Prestipino, F Saija - The Journal of Chemical Physics, 2014 - pubs.aip.org
Two-dimensional crystals of classical particles are very peculiar in that melting may occur in
two steps, in a continuous fashion, via an intermediate hexatic fluid phase exhibiting quasi …

Anomalous phase behavior in a model fluid with only one type of local structure

S Prestipino, F Saija, G Malescio - The Journal of chemical physics, 2010 - pubs.aip.org
We present evidence that the concurrent existence of two populations of particles with
different effective diameters is not a prerequisite for the occurrence of anomalous phase …

The zero-temperature phase diagram of soft-repulsive particle fluids

S Prestipino, F Saija, G Malescio - Soft Matter, 2009 - pubs.rsc.org
Effective pair interactions with a soft-repulsive component are a well-known feature of
polymer solutions and colloidal suspensions, but they also provide a key to interpret the high …

A machine learning approach to analyze the structural formation of soft matter via image recognition

T Terao - Soft Materials, 2020 - Taylor & Francis
ABSTRACT A novel method is developed to analyze the structural formation of colloidal
particles based on image recognition via a convolutional neural network (CNN). This makes …

The Lennard-Jones melting line and isomorphism

DM Heyes, AC Brańka - The Journal of Chemical Physics, 2015 - pubs.aip.org
The location of the melting line (ML) of the Lennard-Jones (LJ) system and its associated
physical properties are investigated using molecular dynamics computer simulation. The …

Phase diagram of spherical particles interacted with harmonic repulsions

YL Zhu, ZY Lu - The Journal of Chemical Physics, 2011 - pubs.aip.org
We construct the phase diagram of spherical particles interacted with harmonic repulsions,
which are ultrasoft and bounded at fully overlapping. This simple potential form can be used …
