Relation between Statics and Dynamics in the Quench of the Ising Model to below the Critical Point
Annalisa Fierro, Antonio Coniglio, Marco Zannetti
The standard phase-ordering process is obtained by quenching a system, like the Ising model, to below the critical point. This is usually done with periodic boundary conditions to…
Condensation of Fluctuations in the Ising Model: a Transition without Spontaneous Symmetry Breaking
Annalisa Fierro, Antonio Coniglio, Marco Zannetti
The ferromagnetic transition in the Ising model is the paradigmatic example of ergodicity breaking accompanied by symmetry breaking. It is routinely assumed that the thermodynamic…
Correlated Percolation
Antonio Coniglio, Annalisa Fierro
Cluster concepts have been extremely useful in elucidating many problems in physics. Percolation theory provides a generic framework to study the behavior of the cluster distributi…
Scaling and universality in glass transition
Antonio de Candia, Annalisa Fierro, Antonio Coniglio
Kinetic facilitated models and the Mode Coupling Theory (MCT) model B are within those systems known to exhibit a discontinuous dynamical transition with a two step relaxation. We…
Percolation approach to glassy dynamics with continuously broken ergodicity
Jeferson J. Arenzon, Antonio Coniglio, Annalisa Fierro +1
We show that the relaxation dynamics near a glass transition with continuous ergodicity breaking can be endowed with a geometric interpretation based on percolation theory. At mean…
Dynamical arrest: interplay of the glass and of the gel transitions
Nagi Khalil, Antonio Coniglio, Antonio de Candia +2
The structural arrest of a polymeric suspension might be driven by an increase of the cross--linker concentration, that drives the gel transition, as well as by an increase of the…
Size segregation in granular media induced by phase transition
M. Tarzia, A. Fierro, M. Nicodemi +2
In order to study analytically the nature of the size segregation in granular mixtures, we introduce a mean field theory in the framework of a statistical mechanics approach, based…
Complex viscosity behavior and cluster formation in attractive colloidal systems
F. Mallamace, S. H. Chen, A. Coniglio +3
The increase of the viscosity, which is observed in attractive colloidal systems by varying the temperature or the volume fraction, can be related to the formation of structures du…
Jamming transition in granular media: A mean field approximation and numerical simulations
A. Fierro, M. Nicodemi, M. Tarzia +2
In order to study analytically the nature of the jamming transition in granular material, we have considered a cavity method mean field theory, in the framework of a statistical me…
Segregation in fluidized versus tapped packs
Marco Tarzia, Annalisa Fierro, Mario Nicodemi +1
We compare the predictions of two different statistical mechanics approaches, corresponding to different physical measurements, proposed to describe binary granular mixtures subjec…
Statistical Mechanics of segregation in binary granular mixtures
M. Tarzia, A. Fierro, M. Nicodemi +2
We discuss mixing/segregation phenomena in a schematic hard spheres lattice model for binary mixtures of granular media, by analytical evaluation, within Bethe-Peierls approximatio…
Statistical Mechanics of jamming and segregation in granular media
M. Nicodemi, A. Coniglio, A. de Candia +3
In the framework of schematic hard spheres lattice models we discuss Edwards' Statistical Mechanics approach to granular media. As this approach appears to hold here to a very good…
Glass transition in granular media
M. Tarzia, A. de Candia, A. Fierro +2
In the framework of schematic hard spheres lattice models for granular media we investigate the phenomenon of the ``jamming transition''. In particular, using Edwards' approach, by…
Thermodynamics and statistical mechanics of frozen systems in inherent states
Annalisa Fierro, Mario Nicodemi, Antonio Coniglio
We discuss a Statistical Mechanics approach in the manner of Edwards to the ``inherent states'' (defined as the stable configurations in the potential energy landscape) of glassy s…
Segregation in hard spheres mixtures under gravity. An extension of Edwards approach with two thermodynamical parameters
Mario Nicodemi, Annalisa Fierro, Antonio Coniglio
We study segregation patterns in a hard sphere binary model under gravity subject to sequences of taps. We discuss the appearance of the ``Brazil nut'' effect (where large particle…
Autocorrelation functions in 3D fully frustrated systems
G. Franzese, A. Fierro, A. De Candia +1
We present a numerical study of autocorrelation functions of a 3D Fully Frustrated Ising model (FFIM) simulated by spin-flip Monte Carlo dynamics, finding simple exponential decay…
Equilibrium Distribution of the Inherent States and their Dynamics in Glassy Systems and Granular Media
Annalisa Fierro, Mario Nicodemi, Antonio Coniglio
The present paper proposes a Statistical Mechanics approach to the inherent states of glassy systems and granular materials, following the original ideas developed by Edwards for g…
Percolation transition and the onset of non exponential relaxation in fully frustrated models
A. Fierro, G. Franzese, A. de Candia +1
We numerically study the dynamical properties of fully frustrated models in 2 and 3 dimensions. The results obtained support the hypothesis that the percolation transition of the K…
Non exponential relaxation in fully frustrated models
A. Fierro, A. de Candia, A. Coniglio
We study the dynamical properties of the fully frustrated Ising model. Due to the absence of disorder the model, contrary to spin glass, does not exhibit any Griffiths phase, which…
