One dimensional Potts model with many-body interactions and the Generalized Model of Polypeptide Chain for the helix-coil transition
Artem Badasyan, Achille Giacometti, Rudolf Podgornik +2
Helix-coil transition in polypeptides is an example of a spin model with a preferred spin direction, in the sense that a theoretical formulation of this problem requires to assign…
Emergence of Secondary Motifs in Tube-Like Polymers in a Solvent
Chiara Poletto, Achille Giacometti, Antonio Trovato +2
We study the effects of two kinds of interactions in tube-like polymers and demonstrate that they result in the formation of secondary motifs. The first has an entropic origin and…
Patchy sticky hard spheres: analytical study and Monte Carlo simulations
Riccardo Fantoni, Domenico Gazzillo, Achille Giacometti +2
We consider a fluid of hard spheres bearing one or two uniform circular adhesive patches, distributed so as not to overlap. Two spheres interact via a ``sticky'' Baxter potential i…
Phase behavior of polydisperse sticky hard spheres: analytical solutions and perturbation theory
Domenico Gazzillo, Achille Giacometti, Riccardo Fantoni
We discuss phase coexistence of polydisperse colloidal suspensions in the presence of adhesion forces. The combined effect of polydispersity and Baxter's sticky-hard-sphere (SHS) p…
Collective dynamics in coupled maps on a lattice with quenched disorder
Achille Giacometti, Maurice Rossi, Libero Battiston
It is investigated how a spatial quenched disorder modifies the dynamics of coupled map lattices. The disorder is introduced via the presence or absence of coupling terms among lat…
The thermodynamic instabilities of a binary mixture of sticky hard spheres
Riccardo Fantoni, Domenico Gazzillo, Achille Giacometti
The thermodynamic instabilities of a binary mixture of sticky hard spheres (SHS) in the modified Mean Spherical Approximation (mMSA) and the Percus-Yevick (PY) approximation are in…
