Saddles and softness in simple model liquids
L. Angelani, C. De Michele, G. Ruocco +1
We report a numerical study of saddles properties of the potential energy landscape for soft spheres with different softness, i.e. different power n of the interparticle repulsive…
Topology and phase transitions: from an exactly solvable model to a relation between topology and thermodynamics
Luca Angelani, Lapo Casetti, Marco Pettini +2
The elsewhere surmised topological origin of phase transitions is given here new important evidence through the analytic study of an exactly solvable model for which both topology…
Aging under Shear: Structural Relaxation of a Non-Newtonian Fluid
R. Di Leonardo, F. Ianni, G. Ruocco
The influence of an applied shear field on the dynamics of an aging colloidal suspension has been investigated by the dynamic light scattering determination of the density autocorr…
Comment on "Collective dynamics in liquid lithium, sodium, and aluminum"
Tullio Scopigno, Giancarlo Ruocco
In a recent paper, S. Singh and K. Tankeshwar (ST), [Phys. Rev. E \textbf{67}, 012201 (2003)], proposed a new interpretation of the collective dynamics in liquid metals, and, in pa…
Evidence of anomalous dispersion of the generalized sound velocity in glasses
B. Ruzicka, T. Scopigno, S. Caponi +7
The dynamic structure factor, S(Q,w), of vitreous silica, has been measured by inelastic X-ray scattering in the exchanged wavevector (Q) region Q=4-16.5 nm-1 and up to energies hw…
Routes to gelation in a clay suspension
B. Ruzicka, L. Zulian, G. Ruocco
The gelation of water suspension of a synthetic clay (Laponite) has been studied by dynamic light scattering in a wide range of clay weight concentration (Cw = 0.003-0.031). At var…
