A fluctuation-free pathway for a topological magnetic phase transition
Riccardo Battistelli, Lukas Körber, Kai Litzius +27
Topological magnetic textures are particle-like spin configurations stabilized by competing interactions. Their formation is commonly attributed to fluctuation-driven, first-order…
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,…
Coherent control of Floquet-engineered magnon frequency combs
Christopher Heins, Amelie L. Fehrmann, Lukas Körber +5
Frequency combs represent a hallmark of coherence emerging from nonlinear dynamics, where periodic driving organizes energy into a precisely spaced spectral structure. Extending th…
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.…
Toroidal Moments in Confined Nanomagnets and their Impact on Magnonics
Felipe Brevis, Lukas Körber, B. Mimica-Figari +3
The nonreciprocity created by dipolar coupling, electric currents, and Dzyaloshinskii-Moriya interactions is discussed in cases where the magnon propagation direction has a compone…
