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…
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…
