Active Rheology and Anti-Commensuration Effects For Driven Probe Particles on Two Dimensional Periodic Pinning Substrates
C. J. O. Reichhardt, C. Reichhardt
For an assembly of particles interacting with a two dimensional periodic substrate, a series of commensuration effects can arise when the number of particles is an integer multiple…
Phonon spectra of a two-dimensional solid dusty plasma modified by two-dimensional periodic substrates
Y. Huang, W. Li, C. Reichhardt +2
Phonon spectra of a two-dimensional (2D) solid dusty plasma modulated by 2D square and triangular periodic substrates are investigated using Langevin dynamical simulations. The com…
Fluctuations and Pinning for Individually Manipulated Skyrmions
C. J. O. Reichhardt, C. Reichhardt
We numerically examine the dynamics of individually dragged skyrmions interacting simultaneously with an array of other skyrmions and quenched disorder. For drives just above depin…
Active Phases for Particles on Resource Landscapes
L. Varga, A. Libal, C. J. O. Reichhardt +1
We introduce an active matter model composed of sterically interacting particles which absorb resources from a substrate and move in response to resource gradients. For varied rati…
Active Matter Shepherding and Clustering in Inhomogeneous Environments
P. Forgacs, A. Libal, C. Reichhardt +1
We consider a mixture of active and passive run-and-tumble disks in an inhomogeneous environment where only half of the sample contains quenched disorder or pinning. The disks are…
Dynamics and Nonmonotonic Drag for Individually Driven Skyrmions
C. Reichhardt, C. J. O. Reichhardt
We examine the motion of an individual skyrmion driven through an assembly of other skyrmions by a constant or increasing force in the absence of quenched disorder. The skyrmion be…
Skyrmion Ratchet in Funnel Geometries
J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2
Using a particle-based model, we simulate the behavior of a skyrmion under the influence of asymmetric funnel geometries and ac driving at zero temperature. We specifically investi…
Clogging, Dynamics and Reentrant Fluid for Active Matter on Periodic Substrates
C. Reichhardt, C. J. O. Reichhardt
We examine the collective states of run-and-tumble active matter disks driven over a periodic obstacle array. When the drive is applied along a symmetry direction of the array, we…
Vortex Ordering and Dynamics on Santa Fe Artificial Ice Pinning Arrays
Wenzhao Li, C. J. O. Reichhardt, B. Jankó +1
We numerically examine the ordering, pinning and flow of superconducting vortices interacting with a Santa Fe artificial ice pinning array. We find that as a function of magnetic f…
