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…

Gauge theory of giant phonon magnetic moment in doped Dirac semimetals
Wenqin Chen, Xiao-Wei Zhang, Ying Su +3
We present a quantum theory of phonon magnetic moment in doped Dirac semimetals. Our theory is based on an emergent gauge field approach to the electron-phonon coupling, applicable…
