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…

M. S. Mrudul, Peter M. Oppeneer
We theoretically investigate the ultrafast generation of spin and orbital magnetism in a two-dimensional gapped Dirac system with spin-orbit coupling. This system is representative…
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…
Nonlinear Optical Spectroscopy of Nodal-Line Semimetals
Navdeep Rana, M. S. Mrudul, Amar Bharti +2
Intense laser-driven nonlinear optical phenomena in two-dimensional (2D) nodal-line semimetals (NLS) exhibit complex mechanisms, particularly in the NbSiTe material sys…
Generation of Phonons with Angular Momentum During Ultrafast Demagnetization
