Anomalous domain wall velocity and Walker breakdown in hybrid systems with anisotropic exchange
(Journal article; Peer reviewed, 2013)It has recently been proposed that spin-transfer torques in magnetic systems with anisotropic exchange can be strongly enhanced, reducing the characteristic current density with up to four orders of magnitude compared to ... -
Anomalous Paths in Quantum Mechanical Path-Integrals
(Journal article; Peer reviewed, 2013)We investigate modifications of the discrete-time lattice action, for a quantum mechanical particle in one spatial dimension, that vanish in the naïve continuum limit but which, nevertheless, induce nontrivial effects due ... -
Anomalous Thermoelectric Effect in Tilted Dirac and Weyl Semimetals
(Master thesis, 2022)Effektive Dirac likninger i topologisk faststoff-fysikk kan, i motsetning til høy-energi ekvivalentene, ha ledd som ikke er Lorentz invariante. Flere slike systemer har blitt oppdaget, både teoretisk og eksperimentelt, ... -
Antideuterons as Signature for Dark Matter
(Master thesis, 2011)In this thesis, we examine the antideuteron spectra from annihilations of dark matter in the form of Weakly Interacting Massive Particles (WIMPs). The so-called coalescence model is commonly used to describe the production ... -
Antiferromagnetic Insulator Spintronics
(Doctoral theses at NTNU;2019:343, Doctoral thesis, 2019)Summary: Spin currents can make your computer energy efficient and ultrafast Have you noticed that your laptop sometimes can get quite warm? Electronical devices rely on transfer of information via a charge current ... -
Antiferromagnetic magnons as highly squeezed Fock states underlying quantum correlations
(Peer reviewed; Journal article, 2019)Employing the concept of two-mode squeezed states from quantum optics, we demonstrate a revealing physical picture for the antiferromagnetic ground state and excitations. Superimposed on a Néel ordered configuration, a ... -
Antiferromagnetic Neuromorphic Computing
(Master thesis, 2022)Nevromorf prosessering er et felt innen datavitenskap som har som mål å designe prosseseringsenheter med inspirasjon fra hjernedynamikk. Når en lager slike prosessorer med tradisjonell halvleder teknologi møter en store ... -
Antimicrobial Properties of Samarium Doped Hydroxyapatite Suspensions and Coatings
(Peer reviewed; Journal article, 2020)Post-implant infections are a major health problem, and it is well-known that treating them with conventional drugs is accompanied by many disadvantages. The development of new biomaterials with enhanced antimicrobial ... -
Antimicrobial Resistance and Biofilms Underlying Catheter-Related Bloodstream Coinfection by Enterobacter cloacae Complex and Candida parapsilosis
(Peer reviewed; Journal article, 2022)Biofilm-associated infections are a public health concern especially in the context of healthcare-associated infections such as catheter-related bloodstream infections (CRBSIs). We evaluated the biofilm formation and ... -
Antinuclei as a Signature of Dark Matter
(Master thesis, 2019)Antideuteron og antihelium er blitt foreslått som en deteksjonskanal for spalting og annihilasjon av mørk materie i Melkeveien på grunn av en forventet lav astrofysisk bakgrunnstøy. I dag er det vanlig å bruke en standard ... -
ApoE Alzheimer’s Disease Aβ-amyloid plaque morphology varies according to APOE isotype
(Peer reviewed; Journal article, 2023)Background: The apolipoprotein E (APOE, gene; apoE, protein) ε4 allele is the most commonly identified genetic risk factor for typical late-onset sporadic Alzheimer’s disease (AD). Each APOE ε4 allele roughly triples the ... -
Application of a long short-term memory for deconvoluting conductance contributions at charged ferroelectric domain walls
(Peer reviewed; Journal article, 2020)Ferroelectric domain walls are promising quasi-2D structures that can be leveraged for miniaturization of electronics components and new mechanisms to control electronic signals at the nanoscale. Despite the significant ... -
Application of Novel Accelerator Research for Particle Therapy
(Master thesis, 2014)This thesis seeks to review the latest trends in hadron therapy devices, and evaluate the potential of novel, researched accelerator concepts for future application. Although the clinical benefits of hadron therapy over ... -
Application of Temporary, Cell-Containing Alginate Microcarriers to Facilitate the Fabrication of Spatially Defined Cell Pockets in 3D Collagen Hydrogels
(Journal article; Peer reviewed, 2021)Mimicking the complexity of natural tissue is a major challenge in the field of tissue engineering. Here, a facile 2-step fabrication method to prepare 3D constructs with distinct regions of high cell concentrations and ... -
Application of the Linear Eddy Model - A Study of Differential Diffusion in Turbulent Hydrogen-Rich Jets
(Master thesis, 2018)Differential diffusion effects in turbulent reactive and non-reactive problems based on hydrogen-rich fuels are not yet fully investigated. Through use of a Fortran implementa-tion of the Linear Eddy Model (LEM) ... -
