On the properties of La0.7Sr0.3MnO3 thin films on (001) SrTiO 3 substrates
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:288, Doctoral thesis, 2012)The performance of spintronic devices are heavily dependent on both the static and dynamic magnetic properties of both their functional interfaces and bulk properties. In this thesis work we study the stoichiometry, ... -
On the Simulation of Electromagnetic Wave Scattering by Periodic and Randomly Rough Layered Structures based on the Reduced Rayleigh Equations: Theory, numerical analysis and applications
(Doctoral theses;2018:306, Doctoral thesis, 2018)A great number of natural phenomena that we observe, as well as numerous man-made objects we use in our everyday life, are made possible thanks to the interaction between light and matter. In particular, when light is ... -
On the Stability of the Local Load Sharing Fiber Bundle Model
(Master thesis, 2016)This thesis investigates a generalized history-independent local load sharing (LLS) fiber bundle model for two dimensional interfacial fractures. When the failure threshold of the fibers are assigned according to the ... -
On the terms violating the custodial symmetry in multi-Higgs-doublet models
(Journal article; Peer reviewed, 2013)We prove that a generic multi-Higgs-doublet model (NHDM) generally must contain terms in the potential that violate the custodial symmetry. This is done by showing that the O(4) violating terms of the NHDM potential cannot ... -
On the three-slit experiment and quantum mechanics
(Journal article; Peer reviewed, 2018)It has been suggested by Sorkin that a three-slit Young experiment could reveal the validity a fundamental ingredient in the foundations of one of the cornerstones in modern physics namely quantum mechanics. In terms of a ... -
On the Use of a Cluster Identification Method and a Statistical Approach for Analyzing Atom Probe Tomography Data for GP Zones in Al–Zn–Mg(–Cu) Alloys
(Peer reviewed; Journal article, 2023)Early-stage clustering in two Al–Mg–Zn(–Cu) alloys has been investigated using atom probe tomography and transmission electron microscopy. Cluster identification by the isoposition method and a statistical approach based ... -
On the use of random walk schemes in oil spill modelling
(Journal article; Peer reviewed, 2019)In oil spill models, vertical mixing due to turbulence is commonly modelled by random walk. If the eddy diffusivity varies with depth, failing to take the derivative of the diffusivity into account in the random walk scheme ... -
On Vanadium Substitution in Li2MnSiO4/C as Positive Electrode for Li-ion Batteries
(Journal article; Peer reviewed, 2016)Vanadium substitution is an interesting approach to manipulate the properties of the poor electronic and ionic conducting lithium transition metal orthosilicates. Especially, if incorporated on the Si site, it could alter ... -
On-board, Fourier-Based Image-Analysis System for Satellite Observation of Gravity Waves
(Master thesis, 2013)The main objective of this thesis is obtaining data on gravity waves from images taken by the NTNU Test Satellite (NUTS). The satellite's main payload consists of a camera intended to capture images of gravity waves in the ... -
On-off switch and sign change for a nonlocal Josephson diode in spin-valve Andreev molecules
(Peer reviewed; Journal article, 2023)Andreev molecules consist of two coherently coupled Josephson junctions and permit nonlocal control over supercurrents. By making the barriers magnetic and thus creating a spin valve, we predict that a nonlocal Josephson ... -
On-shell parameter fixing in the quark-meson model
(Journal article; Peer reviewed, 2017)The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ... -
On-surface manipulation of atom substitution between cobalt phthalocyanine and the Cu(111) substrate
(Journal article; Peer reviewed, 2017)On-surface fabrication of controllable nanostructures is an appealing topic in the field of molecular electronics. Herein, the adsorption of cobalt phthalocyanine (CoPc) on a Cu(111) surface is investigated utilizing a ... -
One-dimensional spin-polarized surface states: A comparison of Bi(112) with other vicinal bismuth surfaces
(Peer reviewed; Journal article, 2023)Vicinal surfaces of bismuth are unique test beds for investigating one-dimensional (1D) spin-polarized surface states that may one day be used in spintronic devices. In this paper, such states have been observed for the ... -
Onsager-symmetry obeyed in athermal mesoscopic systems: Two-phase flow in porous media
(Peer reviewed; Journal article, 2020)We compute the fluid flow time correlation functions of incompressible, immiscible two-phase flow in porous media using a 2D network model. Given a properly chosen representative elementary volume, the flow rate distributions ... -
Ontology-Based Domain Analysis for Model Driven Pervasive Game Development
(Journal article; Peer reviewed, 2018)Domain Analysis (DA) plays an important role in Model Driven Development (MDD) and Domain-Specific Modeling (DSM). However, most formal DA methods are heavy weight and not practical sometimes. For instance, when computer ... -
