Rolling Two-Dimensional Collinear Magnets into Chiral Nanotubes with -Wave Magnetism
Zhejunyu Jin, Robin R. Neumann, Rodrigo Jaeschke-Ubiergo +2
-wave magnets are noncollinear compensated magnetic systems that exhibit nonrelativistic antisymmetric spin splitting in momentum space. Their odd-parity spin symmetry enables u…
Current-driven nonlinear skyrmion dynamics in altermagnets
Yang Liu, Zhejunyu Jin, Jie Liu +1
The center of mass and helicity are two dynamic degrees of freedom of skyrmions. In this work, we study the current-driven skyrmion motion in frustrated altermagnets. Contrary to c…
Alignment-Dependent Gapless Chiral Split Magnons in Altermagnetic Domain Walls
Zhaozhuo Zeng, Zhejunyu Jin, Peng Yan
Altermagnets, an emerging class of magnetic materials, exhibit exotic chiral split magnons that are of great interest for both fundamental physics and spintronic applications. Howe…
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…
Interaction-Driven Altermagnetic Magnon Chiral Splitting
Zhejunyu Jin, Zhaozhuo Zeng, Jie Liu +4
Nonrelativistic magnon chiral splitting in altermagnets has garnered significant recent attention. In this work, we demonstrate that nonlinear three-wave mixing -- where magnons sp…
Frequency comb in twisted magnonic crystals
Minghao Li, Zhejunyu Jin, Zhaozhuo Zeng +1
While twisted magnonic crystals (MCs) have recently gained attention for their intriguing linear phenomena, such as magnon flat bands, their nonlinear dynamics -- particularly the…
