Friction mediated phase transition in confined active nematics
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
Using a minimal continuum model, we investigate the interplay between circular confinement and substrate friction in active nematics. Upon increasing the friction from low to high,…
Ice Rule and Emergent Frustration in Particle Ice and Beyond
Antonio Ortiz-Ambriz, Cristiano Nisoli, Charles Reichhardt +2
Geometric frustration and the ice rule are two concepts that are intimately connected and widespread across condensed matter. The first refers to the inability of a system to satis…
Quenched Dynamics of Artificial Spin Ice: Coarsening versus Kibble-Zurek
A. Libal, A. del Campo, C. Nisoli +2
Artificial spin ices are ideal frustrated model systems in which to explore or design emergent phenomena with unprecedented characterization of the constituent degrees of freedom.…
Active Microrheology, Hall Effect, and Jamming in Chiral Fluids
C. Reichhardt, C. J. O. Reichhardt
We examine the motion of a probe particle driven through a chiral fluid composed of circularly swimming disks. We find that the probe particle travels in both the longitudinal dire…
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,…
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…
