Discovery of a symmetry-driven electronic cascade in a $d$ -wave altermagnet

Zhouyi Yin, Zheng Shi, Shuxuan Zhang +9

Altermagnets host magnetic compensation together with non-relativistic spin-split bands, a coexistence enabled by crystal symmetry. Yet whether and how crystal symmetry organizes c…
