Individual Vortex Manipulation and Stick-Slip Motion in Periodic Pinning Arrays
X. Ma, C. J. O. Reichhardt, C. Reichhardt
We numerically examine the manipulation of vortices interacting with a moving trap representing a magnetic force tip translating across a superconducting sample containing a period…
Avalanches and Criticality in Driven Magnetic Skyrmions
S. A. Diaz, C. Reichhardt, D. P. Arovas +2
We show using numerical simulations that slowly driven skyrmions interacting with random pinning move via correlated jumps or avalanches. The avalanches exhibit power law distribut…
Avalanche Dynamics for Active Matter in Heterogeneous Media
C. J. O. Reichhardt, C. Reichhardt
Using numerical simulations, we examine the dynamics of active matter run-and-tumble disks moving in a disordered array of obstacles. As a function of increasing active disk densit…
Negative Differential Mobility and Trapping in Active Matter Systems
C. Reichhardt, C. J. O. Reichhardt
Using simulations, we examine the average velocity as a function of applied drift force for active matter particles moving through a random obstacle array. We find that for low dri…
Fluctuations and Noise Signatures of Driven Magnetic Skyrmions
Sebastian A. Diaz, C. J. O. Reichhardt, Daniel P. Arovas +2
Magnetic skyrmions are particle-like objects with topologically-protected stability which can be set into motion with an applied current. Using a particle-based model we simulate c…
