Magnetic Skyrmion Interacting with Optical Skyrmion
Lan Bo, Jian Chen, Xichao Zhang +3
Magnetic skyrmions (MSks) and optical skyrmions (OSks) embody topology in matter and in light, respectively. Here we investigate the interaction between a single MSk and an OSk bea…
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…
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…
All-electric control of skyrmion-bimeron transition in van der Waals heterostructures
Lan Bo, Songli Dai, Xichao Zhang +4
Two-dimensional van der Waals materials offer a versatile platform for manipulating atomic-scale topological spin textures. In this study, using first-principles and micromagnetic…
