Author(s): Yiming Li, Mingxiang Pan, Jun Leng, Yuxiao Chen, and Huaqing Huang Altermagnetism, a novel magnetic phase characterized by symmetry-protected, momentum-dependent spin splitting and collinear compensated magnetic moments, has thus far been explored primarily in periodic crystals. In this Letter, we extend the concept of altermagnetism to quasicrystals—aperiodic syst… [Phys. Rev. Lett. 137, 046704] Published Wed Jul 22, 2026
