At low temperatures, glass-forming liquids relax in a simple way
Francesco Rusciano, Raffaele Pastore, Francesco Greco +1
Glass-forming liquids have only a modest tendency to crystallize and hence their dynamics can be studied even below the melting temperature. The relaxation dynamics of most of thes…
Rheological signatures of a glass-glass transition in an aging colloidal clay
Roberta Angelini, Domenico Larobina, Barbara Ruzicka +2
The occurrence of non-equilibrium transitions between arrested states has recently emerged as an intriguing issue in the field of soft glassy materials. The existence of one such t…
Supercooled liquids are Fickian yet non-Gaussian
Francesco Rusciano, Raffaele Pastore, Francesco Greco
Reply to "Comment on 'Fickian non-Gaussian diffusion in glass-forming liquids' ". In [ArXiv:2210.07119v1], Berthier et al. questioned the findings of our letter [Phys. Rev. Lett. 1…
Concentrated suspensions of Brownian beads in water: dynamic heterogeneities trough a simple experimental technique
Raffaele Pastore, Marco Caggioni, Domenico Larobina +2
Concentrated suspensions of Brownian hard-spheres in water are an epitome for understanding the glassy dynamics of both soft materials and supercooled molecular liquids. From an ex…
Origin of Charge Separation at Organic Photovoltaic Heterojunctions: A Mesoscale Quantum Mechanical View
Mosè Casalegno, Raffaele Pastore, Julien Idé +2
The high efficiency of charge generation within organic photovoltaic blends apparently contrasts with the strong "classical" attraction between newly formed electron-hole pairs. Se…
Cage Size and Jump Precursors in Glass-Forming Liquids: Experiment and Simulations
Raffaele Pastore, Giuseppe Pesce, Antonio Sasso +1
Glassy dynamics is intermittent, as particles suddenly jump out of the cage formed by their neighbours, and heterogeneous, as these jumps are not uniformly distributed across the s…
Relaxation functions and dynamical heterogeneities in a model of chemical gel interfering with glass transition
Antonio de Candia, Annalisa Fierro, Raffaele Pastore +2
We investigate the heterogeneous dynamics in a model, where chemical gelation and glass transition interplay, focusing on the dynamical susceptibility. Two independent mechanisms g…
Differential Variance Analysis of soft glassy materials: a direct method to quantify and visualize dynamic heterogeneities
Raffaele Pastore, Giuseppe Pesce, Marco Caggioni
Many amorphous materials show spatially heterogenous dynamics, as different regions of the same system relax at different rates. Such a signature, known as Dynamic Heterogeneity, h…
Cluster structure and dynamics in gels and glasses
Raffaele Pastore, Antonio de Candia, Anallisa Fierro +2
The dynamical arrest of gels is the consequence of a well defined structural phase transition, leading to the formation of a spanning cluster of bonded particles. The dynamical gla…
Cage-jump motion reveals universal dynamics and non-universal structural features in glass forming liquids
Raffaele Pastore, Antonio Coniglio, Antonio de Candia +2
The sluggish and heterogeneous dynamics of glass forming liquids is frequently associated to the transient coexistence of two phases of particles, respectively with an high and low…
Particle jumps in structural glasses
Massimo Pica Ciamarra, Raffaele Pastore, Antonio Coniglio
Particles in structural glasses rattle around temporary equilibriumpositions, that seldom change through a process which is much faster than the relaxation time, known as particle…
Spatial correlations of elementary relaxation events in glass-forming liquids
Raffaele Pastore, Antonio Coniglio, Massimo Pica Ciamarra
The dynamical facilitation scenario, by which localized relaxation events promote nearby relaxation events in an avalanching process, has been suggested as the key mechanism connec…
Connecting short and long time dynamics in hard-sphere-like colloidal glasses
Raffaele Pastore, Massimo Pica Ciamarra, Giuseppe Pesce +1
Glass-forming materials are characterized by an intermittent motion at the microscopic scale. Particles spend most of their time rattling within the cages formed by their neighbors…
Dynamic phase coexistence in glass-forming liquids
R. Pastore, A. Coniglio, M. Pica Ciamarra
One of the most controversial hypotheses for explaining the heterogeneous dynamics of glasses postulates the temporary coexistence of two phases characterized by a high and by a lo…
From cage-jump motion to macroscopic diffusion in supercooled liquids
Raffaele Pastore, Antonio Coniglio, Massimo Pica Ciamarra
The evaluation of the long term stability of a material requires the estimation of its long-time dynamics. For amorphous materials such as structural glasses, it has proven difficu…
Pacman Percolation and the Glass Transition
Raffaele Pastore, Massimo Pica Ciamarra, Antonio Coniglio
We investigate via Monte Carlo simulations the kinetically constrained Kob-Andersen lattice glass model showing that, contrary to current expectations, the relaxation process and t…
'Flow & Jam' of frictional athermal systems under shear stress
Raffaele Pastore, Massimo Pica Ciamarra, Antonio Coniglio
We report recent results of molecular dynamics simulations of frictional athermal particles at constant volume fraction and constant applied shear stress, focusing on a range of co…
Absence of `fragility' and mechanical response of jammed granular materials
Raffaele Pastore, Massimo Pica Ciamarra, Antonio Coniglio
We perform molecular dynamic (MD) simulations of frictional non-thermal particles driven by an externally applied shear stress. After the system jams following a transient flow, we…
Dynamical Correlation Length and Relaxation Processes in a Glass Former
Raffaele Pastore, Massimo Pica Ciamarra, Antonio de Candia +1
We investigate the relaxation process and the dynamical heterogeneities of the kinetically constrained Kob--Anderson lattice glass model, and show that these are characterized by d…
Jamming phase diagram for frictional particles
M. Pica Ciamarra, R. Pastore, M. Nicodemi +1
The non-equilibrium transition from a fluid-like state to a disordered solid-like state, known as the jamming transition, occurs in a wide variety of physical systems, such as coll…
