Group Theory on Quasisymmetry and Protected Near Degeneracy
Jiayu Li, Ao Zhang, Yuntian Liu +1
In solid state systems, group representation theory is powerful in characterizing the behavior of quasiparticles, notably the energy degeneracy. While conventional group theory is…
Catalog of Unconventional Magnons in Collinear Magnets
Xiaobing Chen, Yuntian Liu, Pengfei Liu +5
Topological magnons have garnered significant interest for their potential in both fundamental research and device applications, owing to their exotic, uncharged, yet topologically…
Enumeration and representation theory of spin space groups
Xiaobing Chen, Jun Ren, Yanzhou Zhu +7
Those fundamental physical properties, such as phase transitions, Weyl fermions, and spin excitation, in all magnetic ordered materials, were ultimately believed to rely on the sym…
Chiral Dirac fermion in a collinear antiferromagnet
Ao Zhang, Ke Deng, Jieming Sheng +18
In a Dirac semimetal, the massless Dirac fermion has zero chirality, leading to surface states connected adiabatically to a topologically trivial surface state as well as vanishing…
