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…
Nanofluidic logic based on chiral skyrmion flows
Xichao Zhang, Jing Xia, Yan Zhou +4
Particle-like chiral magnetic skyrmions can flow in nanotracks and behave like chiral fluids. Using interacting flows to perform logical operations is an important topic in microfl…
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…
Bimerons create bimerons: proliferation and aggregation induced by currents and magnetic fields
Xichao Zhang, Yan Zhou, Xiuzhen Yu +1
The aggregation of topological spin textures at nano and micro scales has practical applications in spintronic technologies. Here, the authors report the in-plane current-induced p…
