Schwinger boson study of superconductivity mediated by antiferromagnetic spin-fluctuations
Eirik Erlandsen, Asle Sudbø
We study superconductivity in a normal metal, arising from effective electron-electron interactions mediated by spin-fluctuations in a neighboring antiferromagnetic insulator. Intr…
Plane and Stripe Wave Phases of a Spin-Orbit Coupled Bose-Einstein Condensate in an Optical Lattice with a Zeeman Field
Kristian Mæland, Andreas T. G. Janssønn, Jonas H. Rygh +1
A weakly interacting, spin-orbit coupled, ultracold, dilute Bose gas on a two-dimensional square lattice with an external Zeeman field is studied. We explore the plane and stripe w…
Fingerprints of Universal Spin-Stiffness Jump in Two-Dimensional Ferromagnets
Roberto E. Troncoso, Arne Brataas, Asle Sudbø
Motivated by recent progress on synthesizing two-dimensional magnetic van der Waals systems, we propose a setup for detecting the topological Berezinskii-Kosterlitz-Thouless (BKT)…
Thermal fluctuations and vortex lattice structures in chiral -wave superconductors: robustness of double-quanta vortices
Fredrik Nicolai Krohg, Egor Babaev, Julien Garaud +2
We use large-scale Monte-Carlo simulations to study thermal fluctuations in chiral -wave superconductors in an applied magnetic field in three dimensions. We consider the therma…
Possible odd-frequency Amperean magnon-mediated superconductivity in topological insulator -- ferromagnetic insulator bilayer
Henning G. Hugdal, Asle Sudbø
We study the magnon-mediated pairing between fermions on the surface of a topological insulator (TI) coupled to a ferromagnetic insulator with a tilted mean field magnetization. Ti…
