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 ... -
Non-Universal Critical Exponents ot a Generalized Ashkin-Teller Model

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 ... -
Nonperturbative analysis of the electroweak phase transition in the two Higgs doublet model
(Journal article; Peer reviewed, 2018)We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model, and matching to known ... -
