Stacking-Controlled Altermagnetism and Topological Magnons in Bilayer CrI
Lu Xiao, Meng-Han Zhang, Dao-Xin Yao
Stacked van der Waals magnets provide a tunable route to altermagnetism, a compensated magnetic order characterized by momentum-dependent spin splitting, and to the topological mag…
Higher-order Topological States in Chiral Split Magnons of Honeycomb Altermagnets
Xuan Guo, Meng-Han Zhang, Dao-Xin Yao
We theoretically explore higher-order topological magnons in collinear altermagnets, encompassing a dimensional hierarchy ranging from localized corner modes to propagating hinge e…
Dirac points and Weyl phase in a honeycomb altermagnet
Zhang Meng-Han, Guo Xuan, Dao-Xin Yao
We present unconventional nodal crossings in a two-dimensional (2D) collinear altermagnet, which are enforced by crystal symmetries to lock spin polarization and valley degrees of…
Direct observation of topological magnon edge states
Jihai Zhang, Meng-Han Zhang, Peigen Li +6
Magnon Chern insulators (MCIs) exhibit unique topological magnon band structures featuring chiral edge states. Direct observations of the topologically protected magnon edge states…
Topological magnons in a collinear altermagnet
Meng-Han Zhang, Lu Xiao, Dao-Xin Yao
We propose a model with Weyl magnons and nodal-line magnons () in a collinear altermagnet on the honeycomb lattice. Altermagnetic magnon bands can be realized by brea…
