Continuous-wave broadly tunable high-power Cr:CdS laser
(Journal article; Peer reviewed, 2014)We report spectroscopic characteristics and laser properties of the mid-infrared active laser medium Cr2+:CdS. Temperature-dependent absorption, luminescence and lifetime measurements of the 5E exited state allow determination ... -
Continuous-wave Raman amplification in silicon core fibers pumped in the telecom band
(Peer reviewed; Journal article, 2021)Stimulated Raman amplification is observed for the first time in the silicon core fiber (SCF) platform. The SCFs were tapered to obtain sub-micrometer core dimensions and low optical transmission losses, facilitating ... -
Continuum generation in Mid-IR from Tm-doped germanate fiber using femtosecond Cr:ZnS laser
(Chapter, 2012)The mid-IR supercontinuum generation in fibers has received much attention due to its broad applicability to high-resolution spectroscopy and trace gas analysis, frequency metrology and optical coherence tomography (OCT). ... -
Contrast Enhanced Magnetic Resonance Imaging of Amyloid-β Plaques in a Murine Alzheimer's Disease Model
(Journal article; Peer reviewed, 2023)Background: Early detection of amyloid-β (Aβ) aggregates is a critical step to improve the treatment of Alzheimer’s disease (AD) because neuronal damage by the Aβ aggregates occurs before clinical symptoms are apparent. ... -
Control of magnetic states and spin interactions in bilayer CrCl3 with strain and electric fields: an ab initio study
(Peer reviewed; Journal article, 2023)Using ab initio density functional theory, we demonstrated the possibility of controlling the magnetic ground-state properties of bilayer CrCl3 by means of mechanical strains and electric fields. In principle, we investigated ... -
Control of Magnon Condensates
(Doctoral theses at NTNU;2024:63, Doctoral thesis, 2024)Spintronics is a technology driven field aimed at harnessing the electron spin for novel devices. This is in contrast to traditional electronics, where the electron charge is used as an information carrier. Advances in ... -
Controllable Enhancement of p-Wave Superconductivity via Magnetic Coupling to a Conventional Superconductor
(Peer reviewed; Journal article, 2021)Unconventional superconductors are of high interest due to their rich physics, a topical example being topological edge states associated with p-wave superconductivity. A practical obstacle in studying such systems is the ... -
Controllable spin-transfer torque on an antiferromagnet in a dual spin-valve
(Journal article; Peer reviewed, 2011)We consider current-induced spin-transfer torque on an antiferromagnet (AFM) in a dual spin-valve setup. It is demonstrated that a net magnetization may be induced in the AFM by partially or completely aligning the sublattice ... -
Controllable Superconducting Phase Transition and Magnetization Reorientation due to Spin-Orbit Interactions
(Master thesis, 2019)Vi undersøker to superledende hybridstrukturer og ser på virkningen av å kombinere ulike materialer. Det første systemet består av en enkelt homogen ferromagnet koblet til en superleder, hvor et tynt lag av tungt normalmetall ... -
Controllable vortex loops in superconducting proximity systems
(Journal article; Peer reviewed, 2019)Superconducting vortex loops have so far avoided experimental detection despite being the focus of much theoretical work. We here propose a method of creating controllable vortex loops in the superconducting condensate ... -

Controlled microfluidic emulsification of oil in a clay nanofluid: Role of salt for Pickering stabilization
(Journal article; Peer reviewed, 2016)Research on emulsions is driven by their widespread use in different industries, such as food, cosmetic, pharmaceutical and oil recovery. Emulsions are stabilized by suitable surfactants, polymers, solid particles or a ... -
Controlled mineralisation and recrystallisation of brushite within alginate hydrogels
(Journal article; Peer reviewed, 2016-02)Due to high solubility and fast resorption behaviour under physiological conditions, brushite (CaHPO4⋅2H2O, calcium monohydrogen phosphate dihydrate, dicalcium phosphate dihydrate) has great potential in bone regeneration ... -
Controlling microgel fabrication and advancing understanding of bacterial transcriptional regulation by droplet-based microfluidics

Controlling spin supercurrents via nonequilibrium spin injection
(Journal article; Peer reviewed, 2019)We propose a mechanism whereby spin supercurrents can be manipulated in superconductor/ferromagnet proximity systems via nonequilibrium spin injection. We find that if a spin supercurrent exists in equilibrium, a nonequilibrium ... -
Controlling superconducting spin flow with spin-flip immunity using a single homogeneous ferromagnet
