Planar Interfaces for Transmission of Chiral Spin Textures
Robin Msiska, Cynthia J. O. Reichhardt, Charles Reichhardt +2
Lateral magnetic interfaces provide a direct way to test whether skyrmions remain robust when driven across abrupt changes in material parameters and magnetic order. Here we study…
Diffusion asymmetry of repulsive skyrmions in structured environment
Xichao Zhang, Charles Reichhardt, Cynthia J. O. Reichhardt +5
The diffusion of matter in structured environments can give rise to emergent phenomena that do not occur in unstructured environments. Here, we report the asymmetric diffusion of m…
Phase Time Crystals and Pairing in Binary Active Chiral Systems
C. Reichhardt, C. J. O. Reichhardt
We introduce a class of dynamic systems we call phase time crystals consisting of a binary assembly of particles with intermediate or long-range repulsive interactions that are sub…
Janus skyrmion: Interfacial quasiparticle with two-faced helicity
Xichao Zhang, Rui Zhang, Qiming Shao +4
Janus particles are functional particles with at least two surfaces showing asymmetric properties. We show at the interface between two magnetic regions with different antisymmetri…
Analytical model for the motion and interaction of two-dimensional active nematic defects
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
We develop an approximate, analytical model for the velocity of defects in active nematics by combining recent results for the velocity of topological defects in nematic liquid cry…
Polarization and dynamic phases of aligning active matter in periodic obstacle arrays
Daniel Canavello, C. Reichhardt, C. J. O Reichhardt +1
We numerically examine a system of monodisperse self-propelled particles interacting with each other via simple steric forces and aligning torques moving through a periodic array o…
