Collective flow in single-hit QCD kinetic theory
(Peer reviewed; Journal article, 2021-11)Motivated by recent interest in collectivity in small systems, we calculate the harmonic flow response to initial geometry deformations within weakly coupled QCD kinetic theory using the first correction to the free-streaming ... -
Collider phenomenology of a unified leptoquark model
(Peer reviewed; Journal article, 2020-05)We demonstrate that in a recently proposed unified leptoquark model based on the gauge group SU(4)C×SU(2)L×U(1) R significant deviations from the Standard Model values of R K and R K ∗ can be accommodated without any need ... -
Comment on ''Szekeres universes with homogeneous scalar fields''
(Peer reviewed; Journal article, 2021-04)In two recently published articles, Barrow and Paliathanasis (2018, 2019) [1, 2] claim to have found exact solutions of Einstein’s field equations belonging to the class of non-trivial (i.e., spatially inhomogeneous) ... -
Competing risk analysis of Norwegian mortality
(Masteroppgave/UIS-TN-IMF/2019;, Master thesis, 2019-06)Survival data analysis is a set of statistical methodologies that is used to model time until a certain event occurs. Competing risks data arise frequently in survival data from medical research in situations when individuals ... -
Competition of chiral soliton lattice and Abrikosov vortex lattice in QCD with isospin chemical potential
(Peer reviewed; Journal article, 2022-04)We investigate the thermodynamics of two-flavor quark matter in presence of nonzero isospin chemical potential and external magnetic field. It is known that at sufficiently high isospin chemical potential, charged pions ... -
Complex Analysis the Hard Way: a Measure Theoretical Approach
(Master thesis, 2023)In this thesis we present a sophisticated, non-standard treatment of complex analysis using modern tools from measure theory and advanced analysis. This approach opens the path to deep and powerful results, including the ... -
The complex heavy-quark potential in an anisotropic quark-gluon plasma — Statics and dynamics
(Peer reviewed; Journal article, 2022)We generalize a complex heavy-quark potential model from an isotropic QCD plasma to an anisotropic one by replacing the Debye mass mD with an anisotropic screening mass depending on the quark pair alignment with respect ... -
Connecting analysis, algebra, and topology; Generalizing Maxwell's equations
(Bachelor thesis, 2023)This thesis explores the mathematical concepts of differential forms and their applications in higher dimensional geometries, known as manifolds. We will see how the topological invariants of a geometry are related to ... -
Connecting the Dots: Numerical Randomized Hamiltonian Monte Carlo with State-Dependent Event Rates
(Peer reviewed; Journal article, 2022)Numerical generalized randomized Hamiltonian Monte Carlo is introduced, as a robust, easy to use and computationally fast alternative to conventional Markov chain Monte Carlo methods for continuous target distributions. A ... -
Correlated insulators in twisted bilayer graphene
(Peer reviewed; Journal article, 2021-03)Experiments on graphene bilayers, where the top layer is rotated with respect to the one below, have displayed insulating behavior when the moiré bands are partially filled. We calculate the charge distributions in these ... -
Correlating confinement to topological fluctuations near the crossover transition in QCD
(Peer reviewed; Journal article, 2022)We show the existence of strong (anti)correlations between the topological hot spots and the local values of the trace of the Polyakov loop in 2+1 flavor QCD with physical quark mass, in the vicinity of the crossover ... -
Cosmology with the Laser Interferometer Space Antenna
(Peer reviewed; Journal article, 2023)The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications ... -
Crystal field effects in the zig-zag chain compound SrTm2O4
(Peer reviewed; Journal article, 2022)The single ion properties of the zig-zag chain compound SrTm2O4 have been investigated using heat capacity, magnetic susceptibility, magnetization, inelastic neutron scattering, and polarized muon spectroscopy. Two crystal ... -
DD¯ ∗ scattering and χc1(3872) in nuclear matter
(Peer reviewed; Journal article, 2021-09)We study the behavior of the χc1(3872), also known as X(3872), in dense nuclear matter. We begin from a picture in vacuum of the X(3872) as a purely molecular (DD¯¯¯∗-c.c) state, generated as a bound state from a heavy-quark ... -
Den deriverte, tangenter og elevers forståelse av disse.
(Master thesis, 2021)I dette forskningsarbeidet forsøker jeg å få et innblikk i elever med fagene S2 og R2 sin forståelse av den deriverte og tangenter. Hva slags begrepsforståelse har elevene? Er deres forståelse instrumentell og/eller ... -
Derivations of the Young-Laplace equation
(Journal article, 2021-04)The classical Young-Laplace equation relates capillary pressure to surface tension and the principal radii of curvature of the interface between two immiscible fluids. In this paper the required properties of space curves ... -
Describing mechanical degradation in polymer solution using the FENE-P bead-spring-chain non-Newtonian fluid model.
(Masteroppgave/UIS-TN-IMF/2019;, Master thesis, 2019-06)Polymer solutions are non-Newtonian fluids used in enhanced oil recovery due to their specific properties: Adding high-molecular-weight polymers to injected water significantly increases the apparent viscosity of the latter, ... -
Detecting gravitational waves from cosmological phase transitions with LISA: an update
(Peer reviewed; Journal article, 2020)We investigate the potential for observing gravitational waves from cosmological phase transitions with LISA in light of recent theoretical and experimental developments. Our analysis is based on current state-of-the-art ... -
Determination of lower cut-off levels of adalimumab associated with biochemical remission in Crohn's disease
(Journal article; Peer reviewed, 2019-08)Background and Aim: Adalimumab is administered and dosed using a standardized treatment regimen. Although therapeutic drug monitoring (TDM) may help optimize treatment efficacy, the lower cut-off concentration of adalimumab ... -
