• Magnon decay theory of Gilbert damping in metallic antiferromagnets 

      Simensen, Haakon Thømt; Kamra, Akashdeep; Troncoso, Roberto; Brataas, Arne (Peer reviewed; Journal article, 2020)
      Gilbert damping is a key property governing magnetization dynamics in ordered magnets. We present a theoretical study of intrinsic Gilbert damping induced by magnon decay in antiferromagnetic metals through s−d exchange ...
    • Magnon-polarons in cubic collinear antiferromagnets 

      Simensen, Haakon Thømt; Troncoso, Roberto; Kamra, Akashdeep; Brataas, Arne (Peer reviewed; Journal article, 2019)
      We present a theoretical study of excitations formed by hybridization between magnons and phonons—magnon-polarons—in antiferromagnets. We first outline a general approach to determining which magnon and phonon modes can ...
    • Proximity effect in ballistic superconductor-ferromagnet structures with spin-orbit coupling 

      Simensen, Haakon Thømt (Master thesis, 2017)
      The Bogoliubov-de Gennes equations have been solved numerically for a number of two-dimensional ballistic proximity structures comprised of superconductors, normal metals and ferromagnets, with both interfacial and in-plane ...
    • Tunable superconducting critical temperature in ballistic hybrid structures with strong spin-orbit coupling 

      Simensen, Haakon Thømt; Linder, Jacob (Journal article; Peer reviewed, 2018)
      We present a theoretical description and numerical simulations of the superconducting transition in hybrid structures including strong spin-orbit interactions. The spin-orbit coupling is taken to be of Rashba type for ...
