Pumping magnons with solitons

Congratulations to Medhanie who published his work on spin hydrodynamics on Phys. Rev. B 110, 174424 (2024). This work shows that a rather special solution called a contact soliton dissipative exchange flow can be modulated by spin injection, in turn pumping magnons into the ferromagnetic channel.

This work also extended our pseudospectral Landau-Lifshitz model with spin transfer torque and demonstrated the importance of correctly manage the exchange energy when solitons are present in the system due to their sharp domain walls.
