Twisted magnon frequency combs in ferromagnetic nanorings
Liu Xuejuan, Zheng Xingen, Li Zhengyi +5
We report the emergence of twisted magnon frequency combs (tMFCs) and their higher-order modes in ferromagnetic nanorings, arising from strong nonlinear coupling between vortex-cor…
Helical Magnon Frequency Comb in Synthetic Antiferromagnetic Skyrmion Lattices
Liu Xuejuan, Zheng Xingen, Li Zhixiong +5
Synthetic antiferromagnetic skyrmion lattices (SAF-SkLs), consisting of two ferromagnetic SkLs coupled antiferromagnetically with compensated magnetization, provide a promising pla…
Giant mode splitting of azimuthal spin waves in radial vortices
Zhenyu Wang, Liangrui Li, Xuejuan Liu +3
Radial vortex is a topological spin texture stabilized by the interfacial Dzyaloshinskii-Moriya interaction (DMI) in ferromagnetic disks. Previous investigations have shown that th…
Emergence of Nontrivial Topological Magnon States in Skyrmionium Lattices with Zero Topological Charge
Xingen Zheng, Ping Tang, Xuejuan Liu +3
We predict the emergence of nontrivial topological magnon states in the skyrmionium lattice with zero topological charge. We propose the concept of weighted magnetic flux, which pr…
Topological Magnon Frequency Combs
Zhixiong Li, Xuejuan Liu, Zhejunyu Jin +3
Exploring the synergy between topological physics and nonlinear dynamics unveils profound insights into emergent states of matter. Inspired by recent experimental demonstrations of…
