Superconducting phase transistor in diffusive four-terminal ferromagnetic Josephson junctions
(Journal article, 2012)We study diffusive magnetic Josephson junctions with four superconducting terminals in the weak proximity limit where the leads are arranged in cross form. Employing the linearized Keldysh-Usadel technique, the anomalous ... -
Dissipative quantum phase transitions and high-temperature superconductors
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:229, Doctoral thesis, 2012)This thesis presents seven research papers on topics in condensed-matter theory. Five of the papers report on Monte Carlo studies of quantum phase transitions in various (d+1)-dimensional statistical mechanics models ... -
The impact of wettability alterations on oil release and transport mechanisms in a 2D porous medium
(Master thesis, 2012)The effects of wettability alterations in a 2D network model of a porous media has been studied. By changing the wetting properties of the reservoir through a developed wettability changing algorithm, previously immobile ... -
Soliton delivery of mid-IR femtosecond pulses with ZBLAN fiber
(Journal article; Peer reviewed, 2012)We demonstrate environmentally protected delivery of highpower femtosecond mid-IR pulses in a single-mode ZBLAN fiber by soliton formation. A 70-fs Cr:ZnS laser at 2.4 µm reaches this regime already at ~2 nJ launched pulse ... -
Organic Contaminations in Sub-Marine AC and DC High-Voltage Cables
(Master thesis, 2012)In dielectric insulating materials subjected to alternating electric fields there are energy losses associated with polarization mechanisms and resistivity. A typical dielectric material used for insulation of high voltage ... -
Clay-Oil Droplet Suspensions in Electric Field
(Master thesis, 2012)Silicone oil droplets containing synthetic smectite clay submerged in another immiscible organic oil have been studied by observing clay particle movement, oil circulation and drop deformation when an electric field is ... -
Quantitative 3-D colocalization analysis as a tool to study the intracellular trafficking and dissociation of pDNA-chitosan polyplexes
(Journal article; Peer reviewed, 2012)Multichannel microscopy is frequently used to study intermolecular interactions and spatial relationships between biomolecules and organelles or vesicles in cells. Based on multichannel images, quantitative colocalization ... -
