Pinning, Ordering, and Dynamics of Vortices in Conformal Crystal and Gradient Pinning Arrays
D. Ray, C. Reichhardt, C. J. Olson Reichhardt
We numerically investigate magnetization, pinning, ordering, and dynamics of vortices interacting with pinning arrangements which have a density gradient. We focus on conformal cry…
Softening of Granular Packings with Dynamic Forcing
C. J. Olson Reichhardt, L. M. Lopatina, X. Jia +1
We perform numerical simulations of a two-dimensional bidisperse granular packing subjected to both a static confining pressure and a sinusoidal dynamic forcing applied by a wall o…
Absorbing Phase Transitions and Dynamic Freezing in Running Active Matter Systems
C. Reichhardt, C. J. Olson Reichhardt
We examine a two-dimensional system of sterically repulsive interacting disks where each particle runs in a random direction. This system is equivalent to a run-and-tumble dynamics…
Stripe Systems with Competing Interactions on Quasi-One Dimensional Periodic Substrates
D. McDermott, C. J. Olson Reichhardt, C. Reichhardt
We numerically examine the two-dimensional ordering of a stripe forming system of particles with competing long-range repulsion and short-range attraction in the presence of a quas…
Casimir Effect in Active Matter Systems
D. Ray, C. Reichhardt, C. J. Olson Reichhardt
We numerically examine run-and-tumble active matter particles in Casimir geometries composed of two finite parallel walls. We find that there is an attractive force between the two…
Active Matter Transport and Jamming on Disordered Landscapes
C. Reichhardt, C. J. Olson Reichhardt
We numerically examine the transport of active run-and-tumble particles driven with a drift force over random disordered landscapes comprised of fixed obstacles. For increasing run…
Avalanches and disorder-induced criticality in artificial spin ices
Gia-Wei Chern, C. Reichhardt, C. J. Olson Reichhardt
We show that both square and kagome artificial spin ice systems exhibit disorder-induced nonequilibrium phase transitions, with power law avalanche distributions at the critical di…
