Spin-wave amplification and lasing driven by inhomogeneous spin transfer torques
R. J. Doornenbal, A. Roldán-Molina, A. S. Nunez +1
We show that an inhomogeneity in the spin-transfer torques in a metallic ferromagnet under suitable conditions strongly amplifies incoming spin waves. Moreover, at nonzero temperat…

Spin-vorticity coupling in viscous electron fluids
Ruben J. Doornenbal, Marco Polini, R. A. Duine
We consider spin-vorticity coupling - the generation of spin polarization by vorticity - in viscous two-dimensional electron systems with spin-orbit coupling. We first derive hydro…
