Subharmonic Shapiro steps in depinning dynamics of a 2D solid dusty plasma modulated by 1D nonlinear deformed periodic substrates
Zhaoye Wang, Nichen Yu, Ao xu +4
Langevin dynamical simulations are performed to investigate the depinning dynamics of a two-dimensional solid dusty plasma, which is modulated by one-dimensional nonlinear deformed…
Ratchet Effects in Cyclic Pattern Formation Systems with Competing Interactions
C. Reichhardt, C. J. O. Reichhardt
Ratchet effects can appear for particles interacting with an asymmetric potential under ac driving or for a thermal system in which a substrate is periodically flashed. Here, we sh…
Ordered and Disordered Skyrmion States on a Square Substrate
J. C. Bellizotti Souza, C. J. O. Reichhardt, C. Reichhardt +2
We examine the ordering of skyrmions interacting with a square substrate created from a modulation of anisotropy using atomistic simulations. We consider fillings of {\it f} = 1.5,…
Turbulence to order transitions in activity patterned active nematics
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
We numerically study two-dimensional active nematics with periodic activity patterning. For stripes of activity, we observe a transition from two-dimensional to one-dimensional act…
Shapiro Steps Observed in a Two-Dimensional Yukawa Solid Modulated by a One-Dimensional Vibrational Periodic Substrate
Zhaoye Wang, Nichen Yu, C. Reichhardt +4
Depinning dynamics of a two-dimensional (2D) solid dusty plasma modulated by a one-dimensional (1D) vibrational periodic substrate are investigated using Langevin dynamical simulat…
Cyclic phase transition of substrate-modulated 2D dusty plasma driven by oscillatory forces
Ao Xu, C. Reichhardt, C. J. O. Reichhardt +1
Langevin dynamical simulations are performed to investigate the formation of clusters and voids of a two-dimensional-periodic-substrate (2DPS) modulated two-dimensional dusty plasm…
