Stress transmission in granular matter
Tomaso Aste, Tiziana Di Matteo, Enrico Galleani d'Agliano
The transmission of forces through a disordered granular system is studied by means of a geometrical-topological approach that reduces the granular packing into a set of layers. Th…
Phase equilibria and glass transition in colloidal systems with short-ranged attractive interactions. Application to protein crystallization
Giuseppe Foffi, Gavin D. McCullagh, Aonghus Lawlor +6
We have studied a model of a complex fluid consisting of particles interacting through a hard core and a short range attractive potential of both Yukawa and square-well form. Using…
Mode-Coupling Theory of Colloids with Short-range Attractions
K. A. Dawson, G. Foffi, F. Sciortino +2
Within the framework of the mode-coupling theory of super-cooled liquids, we investigate new phenomena in colloidal systems on approach to their glass transitions. When the inter-p…
Ab-initio study of model guanine assemblies: The role of pi-pi coupling and band transport
R. Di Felice, A. Calzolari, E. Molinari +1
Several assemblies of guanine molecules are investigated by means of first-principle calculations. Such structures include stacked and hydrogen-bonded dimers, as well as vertical c…
Self-assembled guanine ribbons as wide-bandgap semiconductors
A. Calzolari, R. Di Felice, E. Molinari +1
We present a first principle study about the stability and the electronic properties of a new biomolecular solid-state material, obtained by the self-assembling of guanine (G) mole…
Semi-Flexible Polymer in a Uniform Force Field in Two Dimensions
A. Lamura, T. W. Burkhardt, G. Gompper
The conformational properties of a semi-flexible polymer chain, anchored at one end in a uniform force field, are studied in a simple two-dimensional model. Recursion relations are…
A simple approximation for fluids with narrow attractive potentials
D. Pini, A. Parola, L. Reatto
We study a simple modification of the optimized random phase approximation (ORPA) aimed at improving the performance of the theory for interactions with a narrow attractive well by…
Josephson Junction Arrays with Bose-Einstein Condensates
F. S. Cataliotti, S. Burger, C. Fort +5
We report on the direct observation of an oscillating atomic current in a one-dimensional array of Josephson junctions realized with an atomic Bose-Einstein condensate. The array i…
Expansion of a coherent array of Bose-Einstein condensates
P. Pedri, L. Pitaevskii, S. Stringari +6
We investigate the properties of a coherent array containing about 200 Bose-Einstein condensates produced in a far detuned 1D optical lattice. The density profile of the gas, image…
Quenches and crunchs: Does the system explore in aging the same part of the configuration space explored in equilibrium ?
Stefano Mossa, Giancarlo Ruocco, Francesco Sciortino +1
Numerical studies are providing novel information on the physical processes associated to physical aging. The process of aging has been shown to consist in a slow process of explor…
Layer Analysis of the Structure of Water Confined in Vycor Glass
P. Gallo, M. A. Ricci, M. Rovere
A Molecular Dynamics simulation of the microscopic structure of water confined in a silica pore is presented. A single cavity in the silica glass has been modeled as to reproduce t…
Quantum fluctuations in one-dimensional arrays of condensates
Alessandro Cuccoli, Andrea Fubini, Valerio Tognetti +1
The effects of quantum and thermal fluctuations upon the fringe structure predicted to be observable in the momentum distribution of coupled Bose-Einstein condensates are studied b…
A glass transition scenario based on heterogeneities and entropy barriers
A. Crisanti, F. Ritort
We propose a scenario for the glass transition based on the cooperative nature of nucleation processes and entropic effects. The main point is the relation between the off-equilibr…
Dynamic structure of He-Ne mixtures by MD simulation: from hydrodynamic to fast and slow sound modes
Marco Sampoli, Ubaldo Bafile, Eleonora Guarini +1
Molecular dynamics results for the dynamic structure of a He0.77Ne0.23 gas mixture at two densities (15.8 nm-3 and 36.1 nm-3) are presented. A clear description of the crossover fr…
Consequence of superfluidity on the expansion of a rotating Bose-Einstein condensate
Mark Edwards, Charles W. Clark, P. Pedri +2
We study the time evolution of a rotating condensate, that expands after being suddenly released from the confining trap, by solving the hydrodynamic equations of irrotational supe…
Nonlinear excitations in arrays of Bose-Einstein condensates
F. Kh. Abdullaev, B. B. Baizakov, S. A. Darmanyan +2
The dynamics of localized excitations in array of Bose-Einstein condensates is investigated in the framework of the nonlinear lattice theory. The existence of temporarily stable gr…
Modulational instability in cigar shaped Bose-Einstein condensates in optical lattices
V. V. Konotop, M. Salerno
A self consistent theory of a cigar shaped Bose-Einstein condensate (BEC) periodically modulated by a laser beam is presented. We show, both theoretically and numerically, that mod…
Off-equilibrium dynamics in the energy landscape of a simple model glass
R. Di Leonardo, L. Angelani, G. Parisi +3
The aging dynamics of a simple model glass is numerically investigated observing how it takes place in the potential energy landscape . Partitioning the landscape in basins of m…

Antonio Scala, Luca Angelani, Roberto Di Leonardo +2
We review recent results on the potential energy landscape (PES) of model liquids. The role of saddle-points in the PES in connecting dynamics to statics is investigated, confirmin…

C. Fort, P. Maddaloni, F. Minardi +2
A trapped 87Rb Bose-Einstein condensate is initially put into a superposition of two internal states. Under the effect of gravity and by means of a second transition, we prepare tw…
