Transverse ac Driven and Geometric Ratchet Effects for Vortices in Conformal Crystal Pinning Arrays
C. Reichhardt, C. J. Olson Reichhardt
With a series of conformal arrays it is possible to create asymmetric substrates, and it was previously shown that when an ac drive is applied parallel to the asymmetry direction,…
Shapiro Steps for Skyrmion Motion on a Washboard Potential with Longitudinal and Transverse ac Drives
C. Reichhardt, C. J. Olson Reichhardt
We numerically study the behavior of two-dimensional skyrmions in the presence of a quasi-one-dimensional sinusoidal substrate under the influence of externally applied dc and ac d…
Doped Colloidal Artificial Ice
A. Libal, C. J. Olson Reichhardt, C. Reichhardt
We examine square and kagome artificial spin ice for colloids confined in arrays of double-well traps. Unlike magnetic artificial spin ices, colloidal and vortex artificial spin ic…
Magnus-Induced Ratchet Effects for Skyrmions Interacting with Asymmetric Substrates
C. Reichhardt, D. Ray, C. J. Olson Reichhardt
When a particle is driven with an ac force over an asymmetric potential, it can undergo a ratchet effect that produces a net dc motion of the particle. Ratchet effects have been ob…
Avalanches, Plasticity, and Ordering in Colloidal Crystals Under Compression
D. McDermott, C. J. Olson Reichhardt, C. Reichhardt
Using numerical simulations we examine colloids with a long-range Coulomb interaction confined in a two-dimensional trough potential undergoing dynamical compression. As the depth…
Quantized Transport for a Skyrmion Moving on a Two-Dimensional Periodic Substrate
C. Reichhardt, D. Ray, C. J. Olson Reichhardt
We study the dynamics and velocity-force curves of a skyrmion moving over a two-dimensional periodic substrate using simulations of a particle-based skyrmion model, focusing on the…
