Cluster theory of Janus particles
Riccardo Fantoni, Achille Giacometti, Francesco Sciortino +1
We apply a simple statistical mechanics cluster approximation for studying clustering in the Kern and Frenkel model of Janus fluids. The approach is motivated by recent Monte Carlo…
A numerical study of one-patch colloidal particles: from square-well to Janus
Francesco Sciortino, Achille Giacometti, Giorgio Pastore
We perform numerical simulations of a simple model of one-patch colloidal particles to investigate: (i) the behavior of the gas-liquid phase diagram on moving from a spherical attr…
Theoretical description of a DNA-linked nanoparticle self-assembly
Chia Wei Hsu, Francesco Sciortino, Francis W. Starr
Nanoparticles tethered with DNA strands are promising building blocks for bottom-up nanotechnology, and a theoretical understanding is important for future development. Here we bui…
Observation of empty liquids and equilibrium gels in a colloidal clay
Barbara Ruzicka, Emanuela Zaccarelli, Laura Zulian +5
The relevance of anisotropic interactions in colloidal systems has recently emerged in the context of the rational design of new soft materials. Patchy colloids of different shapes…
Effects of patch size and number within a simple model of patchy colloids
Achille Giacometti, Fred Lado, Julio Largo +2
We report on a computer simulation and integral equation study of a simple model of patchy spheres, each of whose surfaces is decorated with two opposite attractive caps, as a func…
From caging to Rouse dynamics in polymer melts with intramolecular barriers: a critical test of the Mode Coupling Theory
Marco Bernabei, Angel J. Moreno, Emanuela Zaccarelli +2
By means of computer simulations and solution of the equations of the Mode Coupling Theory (MCT), we investigate the role of the intramolecular barriers on several dynamic aspects…
