Simulating pure odd-frequency Josephson Junctions with conventional superconductors
(Master thesis, 2022)Vi undersøker proksimitetseffekten i superledende hybridsystemer med iboende Rashba spinn-bane-kobling i likevekt. Motivert av Josephson-effekten i en 1-dimensional S/F/S-struktur med spinn-bane-kobling, først undersøkt ... -
Electron precipitation characteristics during isolated, compound, and multi-night substorm events
(Peer reviewed; Journal article, 2021)A set of 24 isolated, 46 compound, and 36 multi-night substorm events from the years 2008–2013 have been analysed in this study. Isolated substorm events are defined as single expansion–recovery phase pairs, compound ... -
Simulation of the Impurity Photovoltaic Effect in GaAs Solar Cells
(Master thesis, 2021)I dette arbeidet, gjøres numeriske simuleringer for GaAs-solceller med dype urenheter. Slike urenheter fungerer typisk som ødeleggende rekombineringssentre. De kan imidlertid også muliggjøre optisk eksitasjon av ladningsbærere ... -
Transient Heat Transfer to Confined Superfluid Helium
(Doctoral theses at NTNU;2022:202, Doctoral thesis, 2022)To investigate how the Large Hadron Collider at CERN can survive UFO attacks much larger than expected, we build and perform an experiment designed to measure the transient temperature evolution of both a stainless steel ... -
Characterization of TiO2 based thin films using Raman spectroscopy
(Master thesis, 2021)Strukturen til forskjellige TiO2-baserte tynnfilm-prøver ble studert ved bruk av Raman spektroskopi. Prøvene ble deponert på silisium-skiver med to-tommers diameter ved bruk av pulset laser deponering (PLD), og noen ble ... -
Commisioning of MLC parameters by specialized VMAT plans, film dosimetry and complexity analysis
(Master thesis, 2022)VMAT er den mest benyttede behandlingsteknikken innen stråleterapi ved St. Olavs Hospital, og det er viktig å kontrollere at den beregnede dosen samsvarer med den avleverte dosen. Derfor gjennomføres en pasient-spesifikk ... -
Feasibility of Water Equivalent Path Length Analysis in Adaptive Proton Therapy of Locally Advanced Non-Small Cell Lung Cancer
(Master thesis, 2022)Introduksjon: Intensitetsmodulert protonterapi (IMPT) kan potensielt gi betre behandling av lokalavansert ikkje-småcella lungekreft (LA-NSCLC) samanlikna med intensitetsmodulert stråleterapi (IMRT) med foton, som er dagens ... -
Automatic Detection of Air Emboli in The Cerebral Circulation in Newborns By Ultrasound Doppler Technique
(Master thesis, 2022)Når spedbarn er født med hjertesvikt eller en annen form for defekt i hjertet kan det være nødvendig med kateterintervensjon eller hjertekirurgi. Slike inngrep kan føre til at luftbobler blir introdusert inn i blodstrømmen. ... -
Ski lifts, bowling balls, pipe system or waterfall? Lower secondary students’ understanding of analogies for electric circuits.
(Peer reviewed; Journal article, 2020)Electric circuits are challenging for students to understand, and a wide range of analogies are developed in order to support their learning. This article investigates how lower secondary students understand four analogies ... -
Gender Differences in Norwegian Engineering Students’ Understanding of Newtonian Mechanics
(Peer reviewed; Journal article, 2020)An investigation of the gender gap in engineering students’ understanding of Newtonian physics has been done. The results indicate a noticeable gender gap, in addition to an effect due to differences in preparation, i.e. ... -
The Hubble tension and electromagnetic waves in curved spacetime
(Master thesis, 2022)Måling av dagens verdi av Hubble-parameteren H_0 med type 1a supernovaer som standard candles gir H_0 = 73.7+-1.4 km/s/Mpc, mens måling ved hjelp av CMB som standard ruler gir H_0 = 67.4+-0.5 km/s/Mpc. Dette er et problem. ... -
Migrating tide climatologies measured by a high-latitude array of SuperDARN HF radars
(Peer reviewed; Journal article, 2020)This study uses hourly meteor wind measurements from a longitudinal array of 10 high-latitude SuperDARN high-frequency (HF) radars to isolate the migrating diurnal, semidiurnal, and terdiurnal tides at mesosphere–lower-t ... -
Bose–Einstein condensation of nonequilibrium magnons in confined systems
(Peer reviewed; Journal article, 2020)We study the formation of a room temperature magnon Bose–Einstein condensate (BEC) in nanoscopic systems and demonstrate that its lifetime is influenced by the spatial confinement. We predict how dipolar interactions and ... -
“Never at rest”: developing a conceptual framework for descriptions of ‘force’ in physics textbooks
(Peer reviewed; Journal article, 2020)The concept of ‘force’ is abstract and challenging for many physics students, and many studies have revealed misconceptions that hinder students’ understanding and learning in classical physics. One reason for this may be ... -
Phase-controlled spin and charge currents in a superconductor-ferromagnet hybrid
(Peer reviewed; Journal article, 2020)We investigate spin-dependent quasiparticle and Cooper-pair transport through a central node interfaced with two superconductors and two ferromagnets. We demonstrate that voltage biasing of the ferromagnetic contacts induces ... -
Tyrosine Side-Chain Functionalities at Distinct Positions Determine the Chirooptical Properties and Supramolecular Structures of Pentameric Oligothiophenes
(Peer reviewed; Journal article, 2020)Control over the photophysical properties and molecular organization of π-conjugated oligothiophenes is essential to their use in organic electronics. Herein we synthesized and characterized a variety of anionic pentameric ... -
Insulin amyloid polymorphs: implications for iatrogenic cytotoxicity†
(Peer reviewed; Journal article, 2020)Amyloid specific fluorescent probes are becoming an important tool for studies of disease progression and conformational polymorphisms in diseases related to protein misfolding and aggregation such as localized and systemic ... -
Effective Rheology of Bi-viscous Non-newtonian Fluids in Porous Media
(Peer reviewed; Journal article, 2020)We model the flow of bi-viscous non-Newtonian fluids in porous media by a square lattice where the links obey a piece-wise linear constitutive equation. We find numerically that the flow regime, where the network transitions ... -
Highly tunable exchange-only singlet-only qubit in a GaAs triple quantum dot
(Peer reviewed; Journal article, 2020)We propose an implementation of a singlet-only spin qubit in a GaAs-based triple quantum dot with a (1, 4, 1) charge occupation. In the central multielectron dot, the interplay between Coulomb interaction and an out-of-plane ... -
Phase transitions and correlations in fracture processes where disorder and stress compete
(Peer reviewed; Journal article, 2020)We study the effect of the competition between disorder and stress enhancement in fracture processes using the local load sharing fiber bundle model, a model that hovers on the border between analytical tractability and ...
