Heavy quark diffusion in an overoccupied gluon plasma
(Peer reviewed; Journal article, 2020-09)We extract the heavy-quark diffusion coefficient κ and the resulting momentum broadening 〈p2〉 in a far-from-equilibrium non-Abelian plasma. We find several features in the time dependence of the momentum broadening: a short ... -
Heavy quarkonium in extreme conditions
(Peer reviewed; Journal article, 2020)In this report we review recent progress achieved in the understanding of heavy quarkonium under extreme conditions from a theory perspective. Its focus lies both on quarkonium properties in thermal equilibrium, as well ... -
A Heterotic Kodaira--Spencer Theory at One-Loop
(Peer reviewed; Journal article, 2023-10)We consider a heterotic version of six-dimensional Kodaira-Spencer gravity derived from the heterotic superpotential. We compute the one-loop partition function and find it can be expressed as a product of holomorphic ... -
Heterotic quantum cohomology
(Peer reviewed; Journal article, 2022-11)It is believed, but not demonstrated, that the large radius massless spectrum of a heterotic string theory compactified to four-dimensional Minkowski space should obey equations that split into ‘F-terms’ and ‘D-terms’ in ... -
Highly occupied gauge theories in 2+1 dimensions: A self-similar attractor
(Peer reviewed; Journal article, 2019-11)Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar ... -
Hvordan avsløre løgn med statistikk?
(Bachelor thesis, 2021)Hensikten med denne oppgaven er å beskrive vanlige feilkilder/fallgruver i sannsynlighetsregning og statistikk. De ulike feilkildene er beskrevet både skriftlig og matematisk. Oppgaven inneholder forklaringer på hvordan ... -
Hvordan henger økningen av bensinprisen sammen med inflasjonen av den norske kronen?
(Bachelor thesis, 2022)I denne oppgaven er problemstillingen om bensinprisen øker sammen med inflasjonen til den norske kronen. Nå i dag er det mange som klager over at bensinprisene er så høye og at de har økt ekstremt. Da ble en nysgjerrig og ... -
Hydrodynamization in systems with detailed transverse profiles
(Peer reviewed; Journal article, 2020)The observation of fluid-like behavior in nucleus-nucleus (AA), proton-nucleus (pA) and high-multiplicity proton-proton (pp) collisions motivates systematic studies of how different measurements approach their fluid-dynamic ... -
Identification of the flux function of nonlinear conservation laws with variable parameters
(Peer reviewed; Journal article, 2023-09)Machine learning methods have in various ways emerged as a useful tool for modeling the dynamics of physical systems in the context of partial differential equations (PDEs). Nonlinear conservation laws (NCLs) of the form ... -
Importance of endocrine treatment adherence and persistence in breast cancer survivorship: a systematic review
(Peer reviewed; Journal article, 2023)Purpose Adjuvant endocrine treatment is essential for treating luminal subtypes of breast cancer, which constitute 75% of all breast malignancies. However, the detrimental side effects of treatment make it difficult for ... -
Importance Sampling-based Transport Map Hamiltonian Monte Carlo for Bayesian Hierarchical Models
(Peer reviewed; Journal article, 2021-06)We propose an importance sampling (IS)-based transport map Hamiltonian Monte Carlo procedure for performing a Bayesian analysis in nonlinear high-dimensional hierarchical models. Using IS techniques to construct a transport ... -
Improved background subtraction and a fresh look at jet sub-structure in JEWEL
(Peer reviewed; Journal article, 2022)Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed ... -
Improved Gauss law model and in-medium heavy quarkonium at finite density and velocity
(Peer reviewed; Journal article, 2020-03)We explore the in-medium properties of heavy-quarkonium states at finite baryochemical potential and finite transverse momentum based on a modern complex-valued potential model. Our starting point is a novel, rigorous ... -
In-medium kinetic theory of D mesons and heavy-flavor transport coefficients
(Peer reviewed; Journal article, 2022)We extend the kinetic theory of D mesons to accommodate thermal and off-shell effects due to the medium modification of the heavy-meson spectral functions. From the Kadanoff-Baym approach we derive the off-shell Fokker-Planck ... -
Information in Local Curvature: Three Papers on Adaptive Methods in Computational Statistics
(PhD thesis UiS;562, Doctoral thesis, 2020-11)Advanced statistical computations have become increasingly important, as with the increased flexibility of models capturing complex relationships in new data and use-cases, comes increased difficulties of fitting procedures ... -
Inhomogeneous chiral condensate in the quark-meson model
(Journal article, 2017)The two-flavor quark-meson model is used as a low-energy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ... -

Interpolation of weighted extremal functions
(Peer reviewed; Journal article, 2021-03)An approach to interpolation of compact subsets of Cn, including Brunn–Minkowski type inequalities for the capacities of the interpolating sets, was developed in [8] by means of plurisubharmonic geodesics between relative ... -
Introduction to graph theory: Classroom potential of core concepts
(Bachelor thesis, 2021)This thesis is an introduction to graph theory with its core concepts and formulas, including a look at the mostly untapped classroom potential of this field of mathematics. Included are in-depth explanations and proofs ...
