Reversibility, Pattern Formation and Edge Transport in Active Chiral and Passive Disk Mixtures
C. Reichhardt, C. J. O. Reichhardt
We numerically examine mixtures of circularly moving and passive disks as a function of density and active orbit radius. For low or intermediate densities and/or small orbit radii,…
Reversible to Irreversible Transitions in Periodically Driven Skyrmion Systems
B. L. Brown, C. Reichhardt, C. J. O. Reichhardt
We examine skyrmions driven periodically over random quenched disorder and show that there is a transition from reversible motion to a state in which the skyrmion trajectories are…
Ice Rule Fragility via Topological Charge Transfer in Artificial Colloidal Ice
Andras Libal, Don Yun Lee, Antonio Ortiz-Ambriz +4
Artificial particle ices are model systems of constrained, interacting particles. They have been introduced theoretically to study ice-manifolds emergent from frustration, along wi…
Dynamics Phases, Stratification, Laning, and Pattern Formation for Driven Bidisperse Disk Systems in the Presence of Quenched Disorder
D. McDermott, Y. Yang, C. J. O. Reichhardt +1
Using numerical simulations, we examine the dynamics of driven two-dimensional bidisperse disks flowing over quenched disorder. The system exhibits a series of distinct dynamical p…
Laning and Clustering Transitions in Driven Binary Active Matter Systems
C. Reichhardt, J. Thibault, S. Papanikolaou +1
It is well known that a binary system of non-active disks that experience driving in opposite directions exhibits jammed, phase separated, disordered, and laning states. In active…
Clogging and Depinning of Ballistic Active Matter Systems in Disordered Media
C. Reichhardt, C. J. O. Reichhardt
We numerically examine ballistic active disks driven through a random obstacle array. Formation of a pinned or clogged state occurs at much lower obstacle densities for the active…
