Collective Transport Properties of Driven Skyrmions with Random Disorder
C. Reichhardt, D. Ray, C. J. Olson Reichhardt
We use particle-based simulations to examine the static and driven collective phases of skyrmions interacting with random quenched disorder. We show that non-dissipative effects du…
Active Microrheology in Active Matter Systems: Mobility, Intermittency and Avalanches
C. Reichhardt, C. J. Olson Reichhardt
We examine the mobility and velocity fluctuations of a driven particle moving through an active matter bath of self-mobile disks for varied density or area coverage and varied acti…
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…
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…
