We experimentally study the critical properties of the nonequilibrium solid-liquid-like transition that takes place in vibrated granular matter. The critical dynamics is characterized by the coupling of the density field with the bond-orientational order parameter Q(4), which measures the degree of local crystallization. Two setups are compared, which present the transition at different critical accelerations as a result of modifying the energy dissipation parameters. In both setups five… 

Critical phenomena in quasi-two-dimensional vibrated granular systems.

The critical phenomena associated to the liquid-to-solid transition of quasi-two-dimensional vibrated granular systems is studied using molecular dynamics simulations of the inelastic hard sphere model, indicating that two is the lower dimension for having a tricritical point.

Nonequilibrium steady states, coexistence, and criticality in driven quasi-two-dimensional granular matter.

Nonequilibrium steady states of vibrated inelastic frictionless spheres are investigated in quasi-two-dimensional confinement via molecular dynamics simulations and a dynamical mechanism exists that brings about metastable traveling clusters and at the same time stable clusters with anisotropic shapes at low vibration amplitude.

Effective two-dimensional model for granular matter with phase separation.

An effective model, where grains move and collide in two-dimensions is presented, which reproduces the phase transition when the frequency of the periodic forcing is increased and predicts the conditions that must satisfy the energy growth function to obtain the phase separation.

Diffusion and Velocity Correlations of the Phase Transitions in a System of Macroscopic Rolling Spheres

We study an air-fluidized granular monolayer composed of plastic spheres which roll on a metallic grid. The air current is adjusted so that the spheres never lose contact with the grid and so that

Hyperuniform states generated by a critical friction field.

This work shows that a vibrated granular layer, at the critical point of the liquid-to-solid transition, displays dynamic hyperuniformity, and shows that the structure factor detects better the emergence of hyperun uniformity, compared to the particle number variance.

Dynamics of Noncohesive Confined Granular Media

Despite the ubiquitousness and technological and scientific importance of granular matter, our understanding is still very poor compared to molecular fluids and solids. Until today, there is no

Kinetic model for a confined quasi-two-dimensional gas of inelastic hard spheres

The local balance equations for the density, momentum, and energy of a dilute gas of elastic or inelastic hard spheres, strongly confined between two parallel hard plates are obtained. The starting

Dynamic hyperuniform states

Hyperuniform states are the most efficient way to fill up space for disordered systems. In these states the particle distribution is disordered at the short scale but becomes increasingly uniform

Polymer Glass-Formation in Variable Dimension

We explore the nature of glass-formation in variable spatial dimensionality ($d$) based on the generalized entropy theory, a synthesis of the Adam-Gibbs model with direct computation of the

Fluctuations and criticality of a granular solid-liquid-like phase transition.

Results are consistent with model C of dynamical critical phenomena, valid for a nonconserved critical order parameter (bond-orientation order) coupled to a conserved field (density).

Critical-like behaviour of glass-forming liquids.

The glass transition may be a new type of critical phenomenon where a structural order parameter is directly linked to slowness, and a far more direct link than thought before between glass transition and critical phenomena is suggested.

Liquid–solid-like transition in quasi-one-dimensional driven granular media

The theory of non-ideal gases at thermodynamic equilibrium, for instance the van der Waals gas model, has played a central role in our understanding of coexisting phases, as well as the transitions

Capillarylike fluctuations of a solid-liquid interface in a noncohesive granular system.

This work experimentally investigates the coarse-grained solid-liquid interface fluctuations, which are characterized through the static and dynamic correlation functions in the Fourier space and turn out to be well described by the capillary wave theory.

Nonequilibrium critical dynamics of the relaxational models C and D.

The critical dynamics of the n-component relaxational models C and D, which incorporate the coupling of a nonconserved and conserved order parameter S to the conserved energy density rho, under nonequilibrium conditions are investigated by means of the dynamical renormalization group.

Direct observation of medium-range crystalline order in granular liquids near the glass transition.

The existence of long-lived medium-range crystalline order is found to be closely related to both dynamic heterogeneity and slow dynamics, which opens an intriguing possibility of understanding the dynamic arrest in both thermal and athermal systems in a unified manner.

Experimental approaches to universal out-of-equilibrium scaling laws: turbulent liquid crystal and other developments

This is a brief survey of recent experimental studies on out-of-equilibrium scaling laws, focusing on two prominent situations where nontrivial universality classes have been identified

Crystallization of a quasi-two-dimensional granular fluid.

Experimental results for the Lindemann melting criterion, the radial distribution function, the bond order parameter, and the statistics of topological changes at the particle level are the same as those found in simulations of equilibrium hard disks, suggesting the study of equilibrium systems can be effectively applied to study nonequilibrium steady states.

The dynamics of thin vibrated granular layers

We describe a series of experiments and computer simulations on vibrated granular media in a geometry chosen to eliminate gravitationally induced settling. The system consists of a collection of
