Instability of explicit time integration for strongly quenched dynamics with neural quantum states
Hrvoje Vrcan, Johan H. Mentink
Neural quantum states have recently demonstrated significant potential for simulating quantum dynamics beyond the capabilities of existing variational ansätze. However, studying s…
Spin-correlation dynamics: A semiclassical framework for nonlinear quantum magnetism
Lukas Körber, Pim Coenders, Johan H. Mentink
Classical nonlinear theories are highly successful in describing far-from-equilibrium dynamics of magnets, encompassing phenomena such as parametric resonance, ultrafast switching,…
Ultrafast coherent magnon spin currents in antiferromagnets
Torstein Hegstad, Johan H. Mentink
Generating coherent magnon spin currents with the highest frequencies and shortest wavelengths is a key challenge in ultrafast spintronics and magnonics. A promising route is to ex…
Effective Theory of Ultrafast Skyrmion Nucleation
Rein Liefferink, Lukas Körber, Kathinka Gerlinger +3
Laser-induced ultrafast skyrmion nucleation has been experimentally demonstrated in several materials. So far, atomistic models have been used to corroborate experimental results.…
Laser-induced helicity and texture-dependent switching of nanoscale stochastic domains in a ferromagnetic film
Dinar Khusyainov, Rein Liefferink, MengXing Na +10
Controlling magnetic textures at ever smaller length and time scales is of key fundamental and technological interest. Achieving nanoscale control often relies on finding an extern…
Spontaneous and impulsive stimulated Raman scattering from two-magnon modes in a cubic antiferromagnet
Anatolii E. Fedianin, Alexandra M. Kalashnikova, Johan H. Mentink
Exchange interactions govern the ordering between microscopic spins and the highest-frequency spin excitations - magnons at the edge of the Brillouin zone. As well known from spont…
