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…
Magnon-mediated superconductivity on the surface of a topological insulator
Eirik Erlandsen, Arne Brataas, Asle Sudbø
We study superconductivity on the surface of a topological insulator, mediated by magnetic fluctuations in an adjacent ferromagnetic or antiferromagnetic insulator. Superconductivi…
Enhancement of superconductivity mediated by antiferromagnetic squeezed magnons
Eirik Erlandsen, Akashdeep Kamra, Arne Brataas +1
We investigate theoretically magnon-mediated superconductivity in a heterostructure consisting of a normal metal and a two-sublattice antiferromagnetic insulator. The attractive el…
Superfluid Drag in Multicomponent Bose-Einstein Condensates on a Square Optical Lattice
Stian Hartman, Eirik Erlandsen, Asle Sudbø
The superfluid drag-coefficient of a weakly interacting three-component Bose-Einstein condensate is computed deep into the superfluid phase, starting from a Bose-Hubbard model with…
