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…
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…
Strong coupling of chiral magnons in altermagnets
Zhejunyu Jin, Tianci Gong, Jie Liu +4
Altermagnets recently are identified as a new class of magnets that break the time-reversal symmetry without exhibiting net magnetization. The role of the dipole-dipole interaction…
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…
Skyrmion Hall effect in altermagnets
Zhejunyu Jin, Zhaozhuo Zeng, Yunshan Cao +1
It is widely believed that the skyrmion Hall effect is absent in antiferromagnets because of the vanishing topological charge. However, the Aharonov-Casher theory indicates the pos…
