Symmetry-Enforced Chiral Phonons in Altermagnets via Magnon-Phonon Coupling
Philipp Rieger, Markus Weißenhofer, Sergiy Mankovsky +1
Chiral phonons are attractive for spintronics applications, however, their zero-field generation in conventional antiferromagnets is forbidden by combined parity and time-reversal…

Symmetry-Selective Topological Magnon Engineering by Phonon Angular Momentum
Markus Weißenhofer, Philipp Rieger, Chandan K. Singh +3
Dynamical control of Berry curvature remains an outstanding challenge in the engineering of topological phases. Here, we demonstrate control of magnon band structures via coherentl…
