Phase diagram of SALR fluids on spherical surfaces
Stefano Franzini, Luciano Reatto, Davide Pini
We investigate the phase diagram of a fluid of hard-core disks confined to the surface of a sphere and whose interaction potential contains a short-range attraction followed by a l…
On the degeneracy of ordered ground state configurations of the aspherical Gaussian core model
Davide Pini, Markus Weissenhofer, Gerhard Kahl
We provide rigorous evidence that the ordered ground state configurations of a system of parallel oriented, ellipsoidal particles, interacting via a Gaussian interaction (termed in…
Emergence of an Ising critical regime in the clustering of 1D soft matter revealed through string variables
Francesco Mambretti, Simone Molinelli, Davide Pini +2
Soft matter systems are renowned for being able to display complex emerging phenomena such as clustering phases. Recently, a surprising quantum phase transition has been revealed i…
Formation of cluster crystals in an ultra-soft potential model on a spherical surface
Stefano Franzini, Luciano Reatto, Davide Pini
We investigate the formation of cluster crystals with multiply occupied lattice sites on a spherical surface in systems of ultra-soft particles interacting via repulsive, bounded p…
A density-functional theory investigation of cluster formation in an effective-potential model of dendrimers
Davide Pini
We consider a system of particles interacting via a purely repulsive, soft-core potential recently introduced to model effective pair interactions between dendrimers, which is expe…
An investigation of the SCOZA for narrow square-well potentials and in the sticky limit
Davide Pini, Alberto Parola, Jader Colombo +1
We present a study of the self consistent Ornstein-Zernike approximation (SCOZA) for square-well (SW) potentials of narrow width delta. The main purpose of this investigation is to…
Thermodynamic properties of short-range attractive Yukawa fluid: Simulation and theory
Pedro Orea, Carlos Tapia-Medina, Davide Pini +1
Coexistence properties of the hard-core attractive Yukawa potential with inverse-range parameter kappa=9, 10, 12 and 15 are calculated by applying canonical Monte Carlo simulation.…
The smooth cut-off Hierarchical Reference Theory of fluids
Alberto Parola, Davide Pini, Luciano Reatto
We provide a comprehensive presentation of the Hierarchical Reference Theory (HRT) in the smooth cut-off formulation. A simple and self-consistent derivation of the hierarchy of di…
Theory for the phase behaviour of a colloidal fluid with competing interactions
A. J. Archer, C. Ionescu, D. Pini +1
We study the phase behaviour of a fluid composed of particles which interact via a pair potential that is repulsive for large inter-particle distances, is attractive at intermediat…
Nonuniversal routes to universality: Critical phenomena in colloidal dispersions
D. Pini, F. Lo Verso, M. Tau +2
We investigate critical phenomena in colloids by means of the renormalization-group based hierarchical reference theory of fluids (HRT). We focus on three experimentally relevant m…
Fluctuations and Pattern Formation in Fluids with Competing Interactions
A. Imperio, D. Pini, L. Reatto
One of the most interesting phenomena in the soft-matter realm consists in the spontaneous formation of super-molecular structures (microphases) in condition of thermodynamic equil…
A model colloidal fluid with competing interactions: bulk and interfacial properties
A. J. Archer, D. Pini, R. Evans +1
Using a simple mean-field density functional theory theory (DFT), we investigate the structure and phase behaviour of a model colloidal fluid composed of particles interacting via…
Critical behavior in colloid-polymer mixtures: theory and simulation
F. Lo Verso, R. L. C. Vink, D. Pini +1
We extensively investigated the critical behavior of mixtures of colloids and polymers via the two-component Asakura-Oosawa model and its reduction to a one-component colloidal flu…
Freezing and correlations in fluids with competing interactions
D. Pini, A. Parola, L. Reatto
We consider fluids where the attractive interaction at distances slightly larger than the particle size is dominated at larger distances by a repulsive contribution. A previous inv…
Phase transitions in simple and not so simple binary fluids
A. Parola, D. Pini, L. Reatto +1
Compared to pure fluids, binary mixtures display a very diverse phase behavior, which depends sensitively on the parameters of the microscopic potential. Here we investigate the ph…
