Energy landscapes, ideal glasses, and their equation of state
M. S. Shell, P. G. Debenedetti, E. La Nave +1
Using the inherent structure formalism originally proposed by Stillinger and Weber [Phys. Rev. A 25, 978 (1982)], we generalize the thermodynamics of an energy landscape that has a…
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…
Phase diagram of symmetric binary mixtures at equimolar and non-equimolar concentrations: a systematic investigation
D. Pini, M. Tau, A. Parola +1
We consider symmetric binary mixtures consisting of spherical particles with equal diameters interacting via a hard-core plus attractive tail potential with strengths epsilon_{ij},…
Phase separating binary fluids under oscillatory shear
Aiguo Xu, G. Gonnella, A. Lamura
We apply lattice Boltzmann methods to study the segregation of binary fluid mixtures under oscillatory shear flow in two dimensions. The algorithm allows to simulate systems whose…
Dipolar oscillations in a quantum degenerate Fermi-Bose atomic mixture
F. Ferlaino, R. J. Brecha, P. Hannaford +4
We study the dynamics of coupled dipolar oscillations in a Fermi-Bose mixture of K and Rb atoms. This low-energy collective mode is strongly affected by the interspec…
Rheological Behavior of Microemulsions
Giuseppe Gonnella, Marco Ruggieri
We study the stationary and transient behaviors of the microemulsion phase subjected to a shear flow. The system is described by a diffusion-convective equation which generalizes t…
Collective excitations of a trapped Bose-Einstein condensate in the presence of a 1D optical lattice
C. Fort, F. S. Cataliotti, L. Fallani +3
We study low-lying collective modes of a horizontally elongated 87Rb condensate produced in a 3D magnetic harmonic trap with the addition of a 1D periodic potential which is provid…
Computer simulations of domain growth in off-critical quenches of two-dimensional binary mixtures
A. Lamura, G. Gonnella
The phase separation of two-dimensional binary mixtures has been studied through numerical Langevin simulations based on a Ginzburg-Landau free energy. We have considered not symme…
Ordering of the lamellar phase under a shear flow
F. Corberi, G. Gonnella, A. Lamura
The dynamics of a system quenched into a state with lamellar order and subject to an uniform shear flow is solved in the large-N limit. The description is based on the Brazovskii f…
The segregation of sheared binary fluids in the Bray-Humayun model
A. Lamura, G. Gonnella, F. Corberi
The phase separation process which follows a sudden quench inside the coexistence region is considered for a binary fluid subjected to an applied shear flow. This issue is studied…
Soret driven convection in a colloidal solution heated from above at very large solutal Rayleigh number
R. Cerbino, A. Vailati, M. Giglio
Convection in a colloidal suspension with a large negative separation ratio is studied experimentally by heating from above. Shadowgraph observation at very large solutal Rayleigh…
Free energy determination of phase coexistence in model C60: A comprehensive Monte Carlo study
D. Costa, G. Pellicane, M. C. Abramo +1
The free energy of the solid and fluid phases of the Girifalco C60 model are determined through extensive Monte Carlo simulations. In this model the molecules interact through a sp…
Confirmation of Anomalous Dynamical Arrest in attractive colloids: a molecular dynamics study
E. Zaccarelli, G. Foffi, K. A. Dawson +3
Previous theoretical, along with early simulation and experimental, studies have indicated that particles with a short-ranged attraction exhibit a range of new dynamical arrest phe…
Quantum vortices in systems obeying a generalized exclusion principle
G. Kaniadakis, A. M. Scarfone
The paper deals with a planar particle system obeying a generalized exclusion principle (EP) and governed, in the mean field approximation, by a nonlinear Schroedinger equation. We…
Confined water in the low hydration regime
P. Gallo, M. Rapinesi, M. Rovere
Molecular dynamics results on water confined in a silica pore in the low hydration regime are presented. Strong layering effects are found due to the hydrophilic character of the s…
Dynamics of supercooled liquids: density fluctuations and Mode Coupling Theory
E. Zaccarelli, G. Foffi, P. De Gregorio +3
We write equations of motion for density variables that are equivalent to Newtons equations. We then propose a set of trial equations parameterised by two unknown functions to desc…
Observation of an incoherent thermally activated proton hopping process in calix-[4]-arene by means of anelastic spectroscopy
A. Paolone, R. Cantelli, R. Caciuffo +1
The anelastic spectrum of calix[4]arene was measured at two different vibrational frequencies. Three thermally activated peaks were detected. The lowest temperature peak can be des…
Effective wave-equations for the dynamics of cigar-shaped and disc-shaped Bose condensates
L. Salasnich, A. Parola, L. Reatto
Starting from the 3D Gross-Pitaevskii equation and using a variational approach, we derive an effective 1D wave-equation that describes the axial dynamics of a Bose condensate conf…
Evidence for Unusual Dynamical Arrest Scenario in Short Ranged Colloidal Systems
G. Foffi, K. A. Dawson, S. V. Buldyrev +3
Extensive molecular dynamics simulation studies of particles interacting via a short ranged attractive square-well (SW) potential are reported. The calculated loci of constant diff…
Transitions between Inherent Structures in Water
Nicolas Giovambattista, Francis W. Starr, Francesco Sciortino +2
The energy landscape approach has been useful to help understand the dynamic properties of supercooled liquids and the connection between these properties and thermodynamics. The a…
