Polarization and dynamic phases of aligning active matter in periodic obstacle arrays
Daniel Canavello, C. Reichhardt, C. J. O Reichhardt +1
We numerically examine a system of monodisperse self-propelled particles interacting with each other via simple steric forces and aligning torques moving through a periodic array o…
Analytical model for the motion and interaction of two-dimensional active nematic defects
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
We develop an approximate, analytical model for the velocity of defects in active nematics by combining recent results for the velocity of topological defects in nematic liquid cry…
Peak Effect and Dynamics of Stripe and Pattern Forming Systems on a Periodic One Dimensional Substrate
C. Reichhardt, C. J. O. Reichhardt
We examine the ordering, pinning, and dynamics of two-dimensional pattern forming systems interacting with a periodic one-dimensional substrate. In the absence of the substrate, pa…
Dynamic Phases and Combing Effects for Elongated Particles Moving Over Quenched Disorder
A. Libal, S. Stepanov, C. Reichhardt +1
We consider a two-dimensional system of elongated particles driven over a random quenched disorder landscape. For varied pinning site density, external drive magnitude, and particl…
Pattern Formation and Transport for Externally Driven Active Matter on Periodic Substrates
C. Reichhardt, C. J. O. Reichhardt
We investigate the transport of interacting active run-and-tumble particles moving under an external drift force through a periodic array of obstacles for increasing drive amplitud…
Dynamics, Rectification, and Fractionalization for Colloids on Flashing Substrates
A. Libal, C. Reichhardt, B. Janko +1
We show that a rich variety of dynamic phases can be realized for mono- and bidisperse mixtures of interacting colloids under the influence of a symmetric flashing periodic substra…
