Exchange tensors, generalized RKKY interactions, and magnetization dynamics in heterostructures of ferromagnets and topological insulators
Christian Svingen Johnsen, Asle Sudbø
We present a comprehensive theoretical analysis of magnetic heterostructures composed of ferromagnetic (FM) layers interfaced with three-dimensional topological insulators (TIs). I…
Dynamically generated spin-interactions and nutational spin inertia in normal metal-ferromagnet heterostructures
Christian Svingen Johnsen, Asle Sudbø
We consider the spin dynamics of a normal metal-ferromagnet heterostructure, with emphasis on spin-nutation terms arising from a dynamical Ruderman-Kittel-Kasuya-Yosida (RKKY) inte…
Constrained weak-coupling superconductivity in multiband superconductors
Niels Henrik Aase, Christian Svingen Johnsen, Asle Sudbø
We consider superconductivity in a system with Fermi surfaces, including intraband and interband effective electron-electron interactions. The effective interaction is describe…
Quantum Poker A game for quantum computers suitable for benchmarking error mitigation techniques on NISQ devices
Franz G. Fuchs, Vemund Falch, Christian Johnsen
Quantum computers are on the verge of becoming a commercially available reality. They represent a paradigm shift in computing, with a steep learning gradient. The creation of games…
