Quantum Geometry of Altermagnetic Magnons Probed by Light
Rundong Yuan · Wojciech J. Jankowski · Ka Shen · Robert-Jan Slager
Abstract
Author(s): Rundong Yuan, Wojciech J. Jankowski, Ka Shen, and Robert-Jan Slager<br/><p>Magnons with momentum-dependent chirality are a key signature of altermagnets. We identify bicircular light as a smoking-gun optical probe for chiral altermagnetic magnons, selectively targeting their quantum geometry induced by an alternation of magnonic chirality. We show that in -wave altermag…</p><br/>[Phys. Rev. Lett. 137, 106901] Published Tue Sep 01, 2026
