Spin-superfluid-mediated soliton dynamics

Congratulations to Medhanie who published a paper on the interaction between solitons mediated by spin superfluids in Phys. Rev. B. In this study, we nucleated metastable solitons by spin injection. The region between these solitons is a “well” in which a spin superfluid is established. Depending on the relative sign of the initial soliton, the interaction leads to the ejection and renucleation of solitons under the injection region outside or inside of the well.

This work is another step towards the understanding of spin superfluids and their interaction with nonlinear structures.
