Spurious spin nutation modes arising from truncated memory effects
Markus Weißenhofer, Ritwik Mondal, M. S. Mrudul +1
Spin dynamics is conventionally treated as inertia-free. The inertial Landau-Lifshitz-Gilbert equation (iLLG) extends this with a second-order time derivative, predicting a high-fr…
A crystal-field route to THz-driven magnetization
T. Zalewski, M. S. Mrudul, Y. Lee +5
Light carries angular momentum, but the microscopic pathways that transform it into magnetization remain elusive. Here we establish that crystal-field excitations, historically vie…
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…
Huge ultrafast spin Seebeck effect mediated by laser-excited superdiffusive magnon currents
Luca Mikadze, Peter M. Oppeneer, Markus Weißenhofer
Subpicosecond laser excitation of ferromagnetic metals induces strongly nonequilibrium dynamics involving scattering and transport of electrons, phonons, and magnons. Widely used t…
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…
