Altermagnets Enable Gate-Switchable Helical and Chiral Topological Transport with Spin-Valley-Momentum-Locked Dual Protection
Xianzhang Chen, Jiayong Zhang, Bowen Hao +5
We establish a unified, symmetry-driven framework that combines the alternating spin splitting of altermagnets with valley topology to realize and electrically interconvert helical…

Transport signatures of relativistic quantum scars in a graphene cavity
G. Q. Zhang, Xianzhang Chen, Li Lin +5
We study a relativistic quantum cavity system realized by etching out from a graphene sheet by quantum transport measurements and theoretical calculations. The conductance of the g…
