Giant triplet proximity effect in π-biased Josephson junctions with spin-orbit coupling
(Journal article, 2015)In diffusive Josephson junctions the phase difference φ between the superconductors strongly influences the spectroscopic features of the layer separating them. The observation of a uniform minigap and its phase modulation ... -
Gigahertz Femtosecond Cr:ZnS Laser
(Chapter, 2014)We demonstrate the first Cr:ZnS laser with a gigahertz pulse repetition rate. The passively mode-locked by the graphene-based mirror laser provides 105 mW output power with 180 fs pulse duration and 110 pJ pulse energy. -
Ginzburg-Landau Theory for Charge Density Waves and Superconductivity
(Master thesis, 2023)Motivert av den økende interessen for Cuprate-høytemperatur-superledere, tar denne oppgaven for seg samspillet mellom to av dens symmetribrytende faser, superledning og ladningstetthetsbølger. Fra en mikroskopisk teori ... -

Glow Discharge Optical Emission Spectroscopy for Elemental Characterization of Doped TiO2 Thin Films made by Pulsed Laser Deposition
(Master thesis, 2023)Glimutladnings optisk emisjonsspektroskopi (GD-OES) har blitt brukt for å karakterisere tynnfilmprøver fremstilt ved hjelp av pulset laser deponering (PLD). De viktigste prøvene som er analysert er (Cr+N) ko-dopet TiO2-filmer ... -
Going beyond the Chandrasekhar-Clogston limit in a flatband superconductor
(Peer reviewed; Journal article, 2022)The Chandrasekhar-Clogston limit normally places stringent conditions on the magnitude of the magnetic field that can coexist with spin-singlet superconductivity, restricting the critical induced Zeeman shift to a fraction ... -

(Master thesis, 2012)Self-assembled platinum and gold nanostructures, which are formed by evaporation and subsequent diffusion limited aggregation of metal on highly oriented pyrolytic graphite, have been studied by photoemission spectroscopy ... -
Gold Nanostructures on Graphite
(Master thesis, 2013)Gold nanoparticles supported on a graphite substrate are prepared by thermal evaporation, and subsequently studied by X-ray photoelectron spectroscopy (XPS), temperature programmed desorption (TPD) of carbon monoxide and ... -
Goldstone bosons at finite density - Study of spontaneous symmetry breaking in O(N)-symmetric theories at finite chemical potential
(Master thesis, 2017)Goldstone s theorem states that, in presence of Lorentz invariance, the number of massless modes that appear after spontaneous symmetry breaking coincides with the number of broken generators. These modes are called Goldstone ... -
GPU-Accelerated Visualization of Scattered Point Data
(Journal article; Peer reviewed, 2013)As data sets continue to grow in size, visualization has become a vitally important tool for extracting meaningful knowledge. Scattered point data, which are unordered sets of point coordinates with associated measured ... -
Grain boundary structures and their correlation with intergranular corrosion in an extruded Al-Mg-Si-Cu alloy
