Superconductivity at metal-antiferromagnetic insulator interfaces
(Peer reviewed; Journal article, 2019)Magnons in antiferromagnetic insulators couple strongly to conduction electrons in adjacent metals. We show that this interfacial tie can lead to superconductivity in a trilayer consisting of a metal sandwiched between two ... -
Superconductivity in Dirac Materials
(Master thesis, 2016)In this Master s thesis we consider superconductivity in Bravais and bipartite lattice fermion models with nearest neighbour hopping and Rashba-type spin-orbit coupling. The superconductivity is modelled from a negative-U ... -
Superconductivity in the attractive Haldane-Hubbard model
(Master thesis, 2020)Med nylig økt interesse for vekselvirkende topologiske isolatorer som bakteppe ser vi på superledende egenskaper til en attraktiv Haldane-Hubbard-modell. Haldane-Hubbard-modellen har en faseovergang mellom en Chern-isolator ... -
Superconductivity induced by interfacial coupling to magnons
(Journal article; Peer reviewed, 2018)We consider a thin normal metal sandwiched between two ferromagnetic insulators. At the interfaces, the exchange coupling causes electrons within the metal to interact with magnons in the insulators. This electron-magnon ... -
Superconductivity-induced change in magnetic anisotropy in epitaxial ferromagnet-superconductor hybrids with spin-orbit interaction
(Peer reviewed; Journal article, 2020)The interaction between superconductivity and ferromagnetism in thin film superconductor/ferromagnet heterostructures is usually reflected by a change in superconductivity of the S layer set by the magnetic state of the F ... -
Supercontinuum generation in Mid-IR using Chalcogenide and Germanate Nonlinear Fiber
(Journal article; Peer reviewed, 2013)We demonstrate mid-infrared (mid-IR) supercontinuum generation with bandwidth from 2 to 2.8 μm at 20 dB below the peak in nonlinear step-index chalcogenide fiber using femtosecond mid-IR pulses directly from the oscillator. ... -
Supercritical extraction and microwave activation of wood wastes for enhanced syngas production and generation of fullerene-like soot particles
(Peer reviewed; Journal article, 2020)This work demonstrated that supercritical carbon dioxide extraction is effective as a pre-treatment technology to generate soot particles with the fullerene-like structure and increase syngas yield from extracted residues ... -
Supercurrent 0-π oscillations induced by spin-orbit coupling
(Master thesis, 2022)Denne masteroppgaven presenterer det teoretiske rammeverket innen superledning og spinn-bane kobling. Dette rammeverket brukes for å undersøke visse kvanteeffekter i Josephson-overganger (S-X-S). Josephson-overganger består ... -
Supercurrent Induced Proximity Effects at Spin-Orbit Coupled Interfaces
(Master thesis, 2023)Proksimitetseffekt fra å sammenkoble superledere med andre materialer er et aktivt forskningsfelt. Kvanteeffekter som oppstår i slike grensesjikt er interessante både fra et rent teoretisk perspektiv for å forstå fundamental ... -
Supercurrent vortex pinball via a triplet Cooper pair inverse Edelstein effect
(Journal article, 2017)We consider the Josephson effect through a thin spin-orbit coupled layer in the presence of an exchange field h, and discover a set of supercurrent vortices appearing in the system which can be controllably moved around ... -
Supercurrent-induced magnetization dynamics in a Josephson junction with two misaligned ferromagnetic layers
(Journal article; Peer reviewed, 2011)We investigate supercurrent-induced magnetization dynamics in a Josephson junction with two misaligned ferromagnetic layers and demonstrate a variety of effects by solving numerically the Landau-Lifshitz-Gilbert equation. ... -
SuperDARN Observations of Semidiurnal Tidal Variability in the MLT and the Response to Sudden Stratospheric Warming Events
(Journal article; Peer reviewed, 2019)Using meteor wind data from the Super Dual Auroral Radar Network (SuperDARN) in the Northern Hemisphere, we (1) demonstrate that the migrating (Sun‐synchronous) tides can be separated from the nonmigrating components in ... -
Superdense dark matter clumps
(Journal article; Peer reviewed, 2011)We describe the cosmological scenario for the formation of superdense dark matter clumps. As an interesting particular example the case of superheavy neutralino as DMparticles is considered. The small-scale superdense ... -
Superfluidity breakdown and multiple roton gaps in spin-orbit-coupled Bose-Einstein condensates in an optical lattice
(Journal article, 2014)We investigate the superfluid phases of a Rashba spin-orbit-coupled Bose-Einstein condensate residing on a two-dimensional square optical lattice in the presence of an effective Zeeman field Ω. At a critical value Ω=Ωc, ... -
