Non-equilibrium quantum effects in hybrid structures of ferromagnets and superconductors
(Master thesis, 2016)The quasiclassical theory of superconductivity is applied to diffusive nanowires connecting normal-metal and superconducting bulk materials. The diffusion equations for ferromagnetic junctions with spin-orbit coupling are ... -
Non-equilibrium Statistical Mechanics of Two-Phase Flow in Porous Media
(Doctoral theses at NTNU;2016:335, Doctoral thesis, 2016)The world that we live in is a consortium of fluid-solid interactions. The field of two-phase flow in porous materials poses interesting questions regarding such interactions. In this project, we develop a statistical ... -
Non-Fraunhofer Interference Pattern in Inhomogeneous Ferromagnetic Josephson Junctions
(Journal article, 2012)Generic conditions are established for producing a non-Fraunhofer response of the critical supercurrent subject to an external magnetic field in ferromagnetic Josephson junctions. Employing the quasiclassical Keldysh-Usadel ... -
Non-isothermal transport of multi-phase fluids in porous media; The entropy production
(Journal article; Peer reviewed, 2018)We derive the entropy production for transport of multi-phase fluids in a non-deformable, porous medium exposed to differences in pressure, temperature, and chemical potentials. Thermodynamic extensive variables on the ... -
Non-linear optical microscopy as a novel quantitative and label-free imaging modality to improve the assessment of tissue-engineered cartilage
(Journal article; Peer reviewed, 2017)Objective Current systems to evaluate outcomes from tissue-engineered cartilage (TEC) are sub-optimal. The main purpose of our study was to demonstrate the use of second harmonic generation (SHG) microscopy as a novel ... -
Non-linear optical microscopy of cartilage canals in the distal femur of young pigs may reveal the cause of articular osteochondrosis
(Journal article; Peer reviewed, 2017)Background Articular osteochondrosis is a common cause of leg weakness in pigs and is defined as a focal delay in the endochondral ossification of the epiphysis. The first demonstrated steps in the pathogenesis consist ... -
Non-steady 3D dendrite tip growth under diffusive and weakly convective conditions.
(Journal article; Peer reviewed, 2019)Three dimensional α-Al dendrite tip growth under varying solute gradients in an Al-Cu-Si alloy melt has been studied using real time synchrotron X-ray imaging and mathematical modelling. X-radiographic image sequences with ... -

Nonequilibrium magnons from hot electrons in antiferromagnetic systems
(Peer reviewed; Journal article, 2023)We describe a \emph{nonthermal} magnon activation mechanism in antiferromagnetic (AFM) systems via locally equilibrated \emph{spin-unpolarized} hot electrons excited by an ultrafast intense laser pulse. We employ a quantum ... -
Nonlinear Laser-induced Deformations and Forces at Liquid-Liquid Interfaces near the critical Point.
(Master thesis, 2011)The theory of laser-induced liquid-liquid interface deformation has been presented and used to derive a differential equation describing the shape of the deformation. The differential equation has been investigated and ... -
Nonlinear optical microscopy and Raman spectroscopy analysis of Osteoarthritis
(Doctoral thesis at NTNU;2015:113, Doctoral thesis, 2015)Can Osteoarthritis be diagnosed at an early stage? Osteoarthritis (OA) is a highly prevalent, disabling, complex joint disorder, and a leading cause of individual and socioeconomic burden. The tissue that contributes ... -

Nonlinear optical properties of polycrystalline silicon core fibers from telecom wavelengths into the mid-infrared spectral region
(Journal article; Peer reviewed, 2019)Polycrystalline silicon core fibers (SCFs) fabricated via the molten core drawing (MCD) method are emerging as a flexible optoelectronic platform. Here, the optical transmission properties of MCD SCFs that have been tapered ... -
Nonlinear Propagation of mid-IR Femtosecond Pulses in ZBLAN Fiber
(Chapter, 2012)We demonstrate environmentally protected delivery of high-power femtosecond mid-IR pulses in a single-mode ZBLAN fiber by soliton formation. A 70-fs Cr:ZnS laser at 2.4 µm reaches this regime already at ~1.5 nJ launched ... -

Nonlocal Coupling between Antiferromagnets and Ferromagnets in Cavities
(Journal article; Peer reviewed, 2018)Microwaves couple to magnetic moments in both ferromagnets and antiferromagnets. Although the magnons in ferromagnets and antiferromagnets radically differ, they can become entangled via strong coupling to the same microwave ... -
Nonlocal Temporal Interferometry for Highly Resilient Free-Space Quantum Communication
(Peer reviewed; Journal article, 2023)Entanglement distribution via photons over long distances enables many applications, including quantum key distribution, which provides unprecedented privacy. The inevitable degradation of entanglement through noise ... -
