Electric and magnetic signatures of boundary states in topological insulators and superconductors
(Doctoral theses at NTNU;2017:271, Doctoral thesis, 2017)This thesis is based on original research that was carried out in the field of topological phases in quantum condensed matter physics. The results have been published in five papers in Physical Review B, which form the ... -
Electric Cable Ferry: Feasibility study of an electric ferry concept
(Master thesis, 2014)AbstractThe thesis in hand has investigated the feasibility of a cable electric ferry concept. The concept investigated is based on that a short route ferry receives its propulsive power through a cable connected to the ... -
Electric Control of Skyrmion Dynamics and Spin Torque Oscillators in Magnetic Materials with Inversion Asymmetry
(Master thesis, 2016)In this thesis the skyrmion velocity in the presence of spin-transfer torques, Rashba spin-orbit coupling and a constant electric field gradient is derived analytically based on a collective coordinate approach in the ... -
Electric control of superconducting transition through a spin-orbit coupled interface
(Journal article; Peer reviewed, 2016)We demonstrate theoretically all-electric control of the superconducting transition temperature using a device comprised of a conventional superconductor, a ferromagnetic insulator, and semiconducting layers with intrinsic ... -
Electric current and heat production by a neutral carrier: An effect of the axion
(Peer reviewed; Journal article, 2022)A general axion-electrodynamic formalism is presented on the phenomenological level when the environment is dielectric (permittivity and permeability assumed to be constants). Thereafter, a strong and uniform magnetic field ... -
Electric field control of magnon-induced magnetization dynamics in multiferroics
(Journal article; Peer reviewed, 2016)We consider theoretically the effect of an inhomogeneous magnetoelectric coupling on the magnon-induced dynamics of a ferromagnet. The magnon-mediated magnetoelectric torque affects both the homogeneous magnetization and ... -
Electric field dependent polarization switching of tetramethylammonium bromotrichloroferrite(III) ferroelectric plastic crystals
(Peer reviewed; Journal article, 2020)Tetramethylammonium bromotrichloroferrate(III) ([N(CH3)4][FeBrCl3]) is a plastic crystal ferroelectric with small dielectric constant <20 and piezoelectric coefficient as high as 110 pC/N. Here, super-coercive hysteresis ... -
Electric field distribution in layered polymeric HVDC insulation
(Master thesis, 2020)HVDC overføring har blitt mer og mer vanlig ettersom det er foretrukket over HVAC overføring over lengre distanser. Siden kabelen erfarer ulik påkjenning basert på lokale variasjoner innen blant annet temperatur og felt ... -
Electric field nematic alignment of fluorohectorite clay particles in oligomeric matrices
(Journal article, 2013)We study the behavior of fluorohectorite synthetic clay particles dispersed in paraffin wax. We report wide-angle x-ray scattering related to electric-field-induced alignment of the embedded clay particles. The development ... -
Electric Field Simulations of High Voltage DC Extruded Cable Systems
(Journal article, 2017)The market for high voltage DC (HVDC) transmission systems has increased dramatically the last few decades. This is mainly due to the economic, electrical, and environmental advantages for bulk power transmission over long ... -
Electric Generator for Ocean Wave Energy Converter
(Master thesis, 2008)This paper presents design of a Radial Flux Permanent Magnet (RFPM) ring generator for an ocean Wave Energy Converter (WEC). It has a large diameter 61.4 cm and low speed 37.5 rpm. Three phase one layer concentrated winding ... -
Electric Heating of Subsea Pipelines: Design and Testing of an Applicable Ring Core Transformer
(Master thesis, 2013)As it becomes profitable to extract oil and gas from smaller and smaller reservoirs, jumpers (t-offs) connected to the main pipelines become necessary. This master?s thesis has investigated a simple transformer design which ... -
Electric hydraulic interaction
(Master thesis, 2011)The hydraulic models representing hydro turbines and conduit system found instandard model libraries of power system analysis tools are often simplied mod-els. Subsequently, important information about the dynamics of the ... -
