Comparing Dynamics, Pinning and Ratchet Effects for Skyrmionium, Skyrmions, and Antiskyrmions
J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2
We compare the driven dynamics of skyrmions, antiskyrmions, and skyrmionium interacting with random disorder, circular defects, and asymmetric potentials. When interacting with a l…
Reversible to Irreversible Transitions for ac Driven Skyrmions on Periodic Substrates
J. C. Bellizotti Souza, N. P. Vizarim, C. J. O. Reichhardt +2
Using atomistic simulations, we investigate the dynamical behavior of magnetic skyrmions in dimer and trimer molecular crystal arrangements, as well as bipartite lattices at 3/2 an…
Transient Pattern Formation in an Active Matter Contact Poisoning Model
P. Forgacs, A. Libal, C. Reichhardt +2
One of the most notable features in repulsive particle based active matter systems is motility-induced-phase separation (MIPS) where a dense, often crystalline phase coexists with…
Dynamic Phases and Reentrant Hall Effect for Vortices and Skyrmions on Periodic Pinning Arrays
C. J. O. Reichhardt, C. Reichhardt
We consider the motion of superconducting vortices and skyrmions on a square substrate near the first commensurate matching field. Slightly above commensuration, a series of dynami…
Using Active Matter to Introduce Spatial Heterogeneity to the Susceptible-Infected-Recovered Model of Epidemic Spreading
P. Forgacs, A. Libal, C. Reichhardt +2
The widely used susceptible-infected-recovered (S-I-R) epidemic model assumes a uniform, well-mixed population, and incorporation of spatial heterogeneities remains a major challen…
Kibble-Zurek Mechanism for Nonequilibrium Phase Transitions in Driven Systems with Quenched Disorder
C. J. O. Reichhardt, A. del Campo, C. Reichhardt
We numerically study the density of topological defects for a two-dimensional assembly of particles driven over quenched disorder as a function of quench rate through the nonequili…
