    • Magnonic Black Holes 

      Roldán Molina, A.; Núñez Vásquez, Álvaro; Duine, R. A. (American Physical Society, 2017)
      © 2017 American Physical Society.We show that the interaction between the spin-polarized current and the magnetization dynamics can be used to implement black-hole and white-hole horizons for magnons - the quanta of ...
    • Spin-Wave Amplification and Lasing Driven by Inhomogeneous Spin-Transfer Torques 

      Doornenbal, R. J.; Roldán Molina, A.; Núñez Vásquez, Álvaro; Duine, R. A. (American Physical Society, 2019)
      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 temperatures the incoming thermally occupied spin ...
