Kinetics of coagulation phenomena from a granular matter perspective
Gustavo Castillo, Nicolás Mujica
Aggregation processes play a central role in systems ranging from aerosol coagulation and cloud formation to dust growth in protoplanetary disks and granular materials. These proce…
Unjamming in a 3D Granular System: The Micromechanical Role of Friction in Force Distributions and Rheological Properties
Vicente Salinas, Héctor Alarcón, Eduardo Rojas +2
In this work, we investigate the unjamming transition in a three-dimensional granular system composed of frictional spheres, in which the packing fraction is systematically reduced…
Impact of Initial Charge Distributions on the Kinetics of Charged Particle Coagulation
Gustavo Castillo, Nicolás Mujica
We investigate the kinetics of particle aggregation within the framework of the Smoluchowski coagulation equation, extending it to account for electrostatic interactions among char…
Fluid motion for reducing the bounce of partially filled containers
Klebbert Andrade, Javiera Catalán, Juan F. Marín +4
Certain spatial distributions of water inside partially filled containers can significantly reduce the bounce of the container. In experiments with containers filled to a volume fr…
Wave spectroscopy in a driven granular material
Michael Berhanu, Simon Merminod, Gustavo Castillo +1
Driven granular media constitute model systems in out-of-equilibrium statistical physics. By assimilating the motions of granular particles to those of atoms, by analogy, one can o…
Stability of a tilted granular monolayer: How many spheres can we pick before the collapse?
Eduardo Rojas, Héctor Alarcón, Vicente Salinas +2
The triggering of avalanches is investigated using discrete element simulations for a process of random extraction of spheres. A monolayer, formed by identical spheres in a hexagon…
Tuning the distance to the equipartition by controlling the collision rate in a driven granular gas experiment
Gustavo Castillo, Simon Merminod, Eric Falcon +1
In a granular gas experiment of magnetized particles confined in a thin layer, the rate of dissipative collisions is tuned by adjusting the amplitude of an external magnetic field.…
Hyperuniform states generated by a critical friction field
Gustavo Castillo, Nicolas Mujica, Nestor Sepulveda +3
Hyperuniform states are an efficient way to fill up space for disordered systems. In these states the particle distribution is disordered at the short scale but becomes increasingl…
Generation of intermittent gravitocapillary waves via parametric forcing
Gustavo Castillo, Claudio Falcón
We report on the generation of an intermittent wave field driven by a horizontally moving wave maker interacting with Faraday waves. The spectrum of the local gravitocapillary surf…
Universality and criticality of a second-order granular solid-liquid-like phase transition
Gustavo Castillo, Nicolás Mujica, Rodrigo Soto
We experimentally study the critical properties of the non-equilibrium solid-liquid-like transition that takes place in vibrated granular matter. The critical dynamics is character…
Supporting Material for: Capillary-like Fluctuations of a Solid-Liquid Interface in a Non-Cohesive Granular System
Li-Hua Luu, Gustavo Castillo, Nicolás Mujica +1
In this supplementary paper we present some details on the solid-liquid interface detection, the deduction of the non-equilibrium free energy, the analysis of the granular temperat…
Fluctuations and Criticality of a Granular Solid-Liquid-like Phase Transition
Gustavo Castillo, Nicolás Mujica, Rodrigo Soto
We present an experimental study of density and order fluctuations in the vicinity of the solid-liquid-like transition that occurs in a vibrated quasi-two-dimensional granular syst…
