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…

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…
