    • Interplay between superconductivity and ferromagnetism on a topological insulator 

      Linder, Jacob; Tanaka, Yukio; Yokoyama, Takehito; Sudbø, Asle; Nagaosa, Naoto (Journal article; Peer reviewed, 2010)
      We study theoretically proximity-induced superconductivity and ferromagnetism on the surface of a topological insulator. In particular, we investigate how the Andreev-bound states are influenced by the interplay between ...

    • Unconventional Superconductivity on a Topological Insulator 

      Linder, Jacob; Tanaka, Yukio; Yokoyama, Takehito; Sudbø, Asle; Nagaosa, Naoto (Journal article; Peer reviewed, 2010)
      We study proximity-induced superconductivity on the surface of a topological insulator (TI), focusing on unconventional pairing. We find that the excitation spectrum becomes gapless for any spin-triplet pairing, such that ...
