• Antiferromagnetic magnons as highly squeezed Fock states underlying quantum correlations 

      Kamra, Akashdeep; Thingstad, Even; Rastelli, Gianluca; Duine, Rembert A.; Brataas, Arne; Belzig, Wolfgang; Sudbø, Asle (Peer reviewed; Journal article, 2019)
      Employing the concept of two-mode squeezed states from quantum optics, we demonstrate a revealing physical picture for the antiferromagnetic ground state and excitations. Superimposed on a Néel ordered configuration, a ...
    • Chiral Phonon Transport Induced by Topological Magnons 

      Thingstad, Even; Kamra, Akashdeep; Brataas, Arne; Sudbø, Asle (Peer reviewed; Journal article, 2019)
      The plethora of recent discoveries in the field of topological electronic insulators has inspired a search for boson systems with similar properties. There are predictions that ferromagnets on a two-dimensional honeycomb ...
    • Phonon-mediated superconductivity in doped monolayer materials 

      Thingstad, Even; Kamra, Akashdeep; Wells, Justin; Sudbø, Asle (Peer reviewed; Journal article, 2020)
      Insight into why superconductivity in pristine and doped monolayer graphene seems strongly suppressed has been central for the recent years' various creative approaches to realize superconductivity in graphene and graphene-like ...
    • Two-Component Spin-Orbit Coupled Ultracold Atoms in the Weak and Strong Coupling Regimes 

      Thingstad, Even (Master thesis, 2017)
      Motivated by recent experimental advances, we study two-component spin-orbit coupled ultracold bosonic atoms in two dimensions on a square optical lattice. Using a Bose-Hubbard model with spin-conserving and non-spin-conserving ...
