(Master thesis / Masteroppgave, 2009)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In this study, we explore the similarities and differences between variational Monte Carlo techniques that employ conventional and artificial neural network representations of the ground-state wave function for fermionic ...
-
(Doctoral thesis / Doktoravhandling, 2019)I denne avhandlingen har Anders Hafreager utviklet forskningsverktøyet Atomify som syr sammen de forskjellige stegene i et numeriment: planlegging, kjøring og analyse. Ved å kunne se numerimentet i sanntid i et og samme ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The European Council Directive 2013/59/Euratom (BSS Directive) includes optimisation of treatment with radiotherapeutic procedures based on patient dosimetry and verification of the absorbed doses delivered. The present ...

(Master thesis / Masteroppgave, 2011)Organisk uorganiske hybridmaterialer er en relativt ny stoffklasse hvor egenskapene ikke er tilstrekkelig kartlagt. I dette arbeidet er slike materialer laget som tynne filmer med teknikken atomlagdeponering. Filmene er ...
-
(Doctoral thesis / Doktoravhandling, 2010)The archipelago of Svalbard is at daytime located underneath the polar cusp, the window towards the interplanetary space. The polar cusp region is where the solar-terrestrial coupling by a process referred to as magnetic ...
-
(Master thesis / Masteroppgave, 2010)Målsettingen med denne oppgaven var å lage et ekkoloddsystem basert på FPGA-teknologi. Arbeidet med oppgaven er utført med tre hensikter for øyet: 1. Ekkolodd for forskningsanvendelser. 2. System for digitalisering ...
-
(Master thesis / Hovedoppgave, 2005)The ekpyrotic universe is a brane cosmology theory with an alternative explanation of the big bang as a collision between two hyperplanes. We first introduce the reader to brane objects in the context of string theory, and ...
-
(Master thesis / Masteroppgave, 2007)Oppgaven tar for seg analyse av data fra et kjernefysisk forsøk utført ved Oslo syklotronlaboratorium våren 2005. En folie med naturlig nikkel ble bestrålet med helium-ioner. Naturlig nikkel består for det meste av isotopet ...
-
(Master thesis / Masteroppgave, 2013)A study of the laser doping technique from a phosohorus glass layer as a dopant source was carried out. This was done with the purpose of implementing a selective emitter in a crystal silicon solar cell. The main laser ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The elastic waves generated by impactors hitting rough and erodible surfaces are studied. For this purpose, beads of variable materials, diameters, and velocities are dropped on (i) a smooth PMMA plate, (ii) stuck glass ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)I consider neutron electric dipole moment contributions induced by flavor changing Standard Model Higgs boson couplings to quarks. Such couplings might stem from non-renormalizable SU(2)L×U(1)Y invariant Lagrange terms ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)I consider contributions to the neutron electric dipole moment within two-Higgs-doublet models which allow for small flavor changing neutral Higgs couplings. In a previous paper, I considered flavor changing interactions ...
-
(Master thesis / Hovedoppgave, 2004)In this thesis, I will address the so called forward problem of electro-magnetics. That is, given a setup of electrodes on a conductive material, can we compute where the current will pass through? More specifically, from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Droplets covered with densely packed solid particles, often called Pickering droplets, are used in a variety of fundamental studies and practical applications. For many applications, it is essential to understand the ...
-
Electrical and Magnetic Behavior of GdOH Thin Films: A Search for Hydrogen Anion Superconductivity (Chapter / Bokkapittel / SubmittedVersion, 2020)Anomalous resistive and magnetic behavior of GdOH thin films, which belong to the novel class of materials known as oxyhydrides, is reported. The oxyhydrides contain hydrogen in its rare negatively-charged anion state in ...
-
(Doctoral thesis / Doktoravhandling, 2019)This thesis brings together fundamental studies presented in five papers with the focus on the investigation of defects in the wide bandgap semiconductor β-Ga2O3. A broad range of methods was applied; in particular the ...
-
(Doctoral thesis / Doktoravhandling, 2012)Zinc oxide (ZnO) has been used for many years in a wide range of products, but not for its semiconducting properties. Recent improvements made in the production of ZnO generated a new interest towards this material. Indeed, ...
-
(Doctoral thesis / Doktoravhandling, 2013)Electrical characterization of point defects in silicon (Si) is carried out to study fundamental defects present in Si solar cell structures. The interactions between various defect complexes is investigated, while paying ...
-
(Doctoral thesis / Doktoravhandling, 2015)Thermal evolution of impurity-defect complexes in proton-irradiated mono-crystalline silicon material has been investigated by deep level transient spectroscopy (DLTS). Especially, the interaction between common impurities ...
