Twisted magnon frequency combs in ferromagnetic nanorings
Liu Xuejuan, Zheng Xingen, Li Zhengyi +6
We systematically investigate the emergence of twisted magnon frequency combs (tMFCs) and their higher-order modes arising from strong nonlinear coupling between vortex-core gyrati…
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…
Spin-Hall-Like Magnon Transport in a Synthetic Antiferromagnetic Skyrmion Lattice
Xingen Zheng, Xuejuan Liu, Zhenyu Wang +3
We investigate spin-Hall-like magnon edge transport in a synthetic antiferromagnetic skyrmion lattice composed of two antiferromagnetically coupled skyrmion lattice layers with opp…
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…
Low-lying magnon frequency comb in skymion crystals
Xuejuan Liu, Zhejunyu Jin, Zhengyi Li +6
A stable, low-power and tunable magnon frequency comb (MFC) is crucial for magnon-based precision measurements, quantum information processing and chip integration. Original method…
