Structural and Microscopic Relaxation Processes in Liquid Hydrogen Fluoride
R. Angelini, P. Giura, G. Monaco +3
The high frequency collective dynamics of liquid hydrogen fluoride is studied by inelastic x-ray scattering on the coexistence curve at T = 239 K. The comparison with existing mole…
First-principles design of nanomachines
Jayanth R. Banavar, Marek Cieplak, Trinh Xuan Hoang +1
Learning from nature's amazing molecular machines, globular proteins, we present a framework for the predictive design of nano-machines. We show that the crucial ingredients for a…
Colloidal attraction induced by a temperature gradient
R. Di Leonardo, F. Ianni, G. Ruocco
Colloidal crystals are of extreme importance for applied research, such as photonic crystals technology, and for fundamental studies in statistical mechanics. Long range attractive…
Viscoelasticity and Stokes-Einstein relation in repulsive and attractive colloidal glasses
Antonio M. Puertas, Cristiano De Michele, Francesco Sciortino +2
We report a numerical investigation of the visco-elastic behavior in models for steric repulsive and short-range attractive colloidal suspensions, along different paths in the attr…
Multicomponent adhesive hard sphere models and short-ranged attractive interactions in colloidal or micellar solutions
Domenico Gazzillo, Achille Giacometti, Riccardo Fantoni +1
We investigate the dependence of the stickiness parameters -- where the are the conventional Baxter parameters -- on the solute diameters and…
Phase behavior of weakly polydisperse sticky hard spheres: Perturbation theory for the Percus-Yevick solution
Riccardo Fantoni, Domenico Gazzillo, Achille Giacometti +1
We study the effects of size polydispersity on the gas-liquid phase behaviour of mixtures of sticky hard spheres. To achieve this, the system of coupled quadratic equations for the…
RNAlike polymer model: exact calculation on the Bethe lattice
M. Pretti
We consider a lattice polymer model (random walk), in which the walk is allowed to visit lattice bonds at most twice. Such a model might have some relevance to describe statistical…
The ideal glass transition of Hard Spheres
G. Parisi, F. Zamponi
We use the replica method to study the ideal glass transition of a liquid of identical Hard Spheres. We obtain estimates of the configurational entropy in the liquid phase, of the…
Arrested phase separation in a short-ranged attractive colloidal system: A numerical study
G. Foffi, C. De Michele, F. Sciortino +1
We numerically investigate the competition between phase separation and dynamical arrest in a colloidal system interacting via a short ranged attractive potential. Equilibrium flui…
Dynamics in a supercooled liquid of symmetric dumbbells: Reorientational hopping for small molecular elongations
Angel J. Moreno, Song-Ho Chong, Walter Kob +1
We present extensive molecular dynamics simulations of a liquid of symmetric dumbbells, for constant packing fraction, as a function of temperature and molecular elongation. For la…
Thermodynamic anomalies in a lattice model of water: Solvation properties
M. Pretti, C. Buzano
We investigate a lattice-fluid model of water, defined on a 3-dimensional body-centered cubic lattice. Model molecules possess a tetrahedral symmetry, with four equivalent bonding…
Hydration of an apolar solute in a two-dimensional waterlike lattice fluid
C. Buzano, E. De Stefanis, M. Pretti
In a previous work, we investigated a two-dimensional lattice-fluid model, displaying some waterlike thermodynamic anomalies. The model, defined on a triangular lattice, is now ext…

Z. Idziaszek, L. Santos, M. Lewenstein
We study the sympathetic cooling of a trapped Fermi gas interacting with an ideal Bose gas below the critical temperature of the Bose-Einstein condensation. We derive the quantum m…
