Vortex Dynamics, Pinning, and Magic Angles on Moiré Patterns
Wenzhao Li, C. J. O. Reichhardt, B. Jankó +1
We examine pinning and dynamics of Abrikosov vortices interacting with pinning centers placed in a moiré pattern for varied moiré lattice angles. We find a series of magic angles a…
Drive Dependence of the Hall Angle for a Sliding Wigner Crystal in a Magnetic Field
C. Reichhardt, C. J. O. Reichhardt
We numerically examine the depinning and sliding dynamics of a Wigner crystal in the presence of quenched disorder and a magnetic field. In the disorder-free limit, the Wigner crys…
Active Matter Commensuration and Frustration Effects on Periodic Substrates
C. Reichhardt, C. J. O. Reichhardt
We show that self-driven particles coupled to a periodic obstacle array exhibit novel active matter commensuration effects that are absent in the Brownian limit. As the obstacle si…
Continuous and Discontinuous Transitions in the Depinning of Two-Dimensional Dusty Plasmas on a One-Dimensional Periodic Substrate
L. Gu, W. Li, C. Reichhardt +3
Langevin dynamical simulations are performed to study the depinning dynamics of two-dimensional dusty plasmas on a one-dimensional periodic substrate. From the diagnostics of the s…
Guided Skyrmion Motion Along Pinning Array Interfaces
N. P. Vizarim, C. Reichhardt, P. A. Venegas +1
We examine ac driven skyrmions interacting with the interface between two different obstacle array structures. We consider drive amplitudes at which skyrmions in a bulk obstacle la…
Directional Locking Effects for Active Matter Particles Coupled to a Periodic Substrate
C. Reichhardt, C. J. O. Reichhardt
Directional locking occurs when a particle moving over a periodic substrate becomes constrained to travel along certain substrate symmetry directions. Such locking effects arise fo…
Collective Effects and Pattern Formation for Directional Locking of Disks Moving Through Obstacle Arrays
C. Reichhardt, C. J. O. Reichhardt
We examine directional locking effects in an assembly of disks driven through a square array of obstacles as the angle of drive rotates from zero to ninety degrees. For increasing…
Skyrmion Pinball and Directed Motion on Obstacle Arrays
N. P. Vizarim, C. J. O. Reichhardt, P. A. Venegas +1
We examine skyrmions interacting with a square array of obstacles under ac drives applied in one or two directions. For a single direction of ac driving, we find that the Magnus fo…
Shapiro Steps and Nonlinear Skyrmion Hall Angles For dc and ac Driven Skyrmions on a Two Dimensional Periodic Substrate
N. P. Vizarim, C. Reichhardt, P. A. Venegas +1
For an overdamped particle moving over a two-dimensional periodic substrate under combined dc and ac drives, a series of steps can appear in the velocity force curves that are know…
Dynamics of Magnus Dominated Particle Clusters, Collisions, Pinning and Ratchets
C. Reichhardt, C. J. O. Reichhardt
Motivated by the recent work in skyrmions and active chiral matter systems, we examine pairs and small clusters of repulsively interacting point particles in the limit where the dy…
Oscillation-like diffusion of two-dimensional liquid dusty plasmas on one-dimensional periodic substrates with varied widths
W. Li, C. Reichhardt, C. J. O. Reichhardt +2
The long-time diffusion of two-dimensional dusty plasmas on a one-dimensional periodic substrate with varied widths is investigated using Langevin dynamical simulations. When the s…
