Bayesian inference of realtime dynamics from lattice QCD
(Peer reviewed; Journal article, 2022)The computation of dynamical properties of nuclear matter, ranging from parton distribution functions of nucleons and nuclei to transport properties in the quarkgluon plasma, constitutes a central goal of modern theoretical ... 
Bayesian seismic inversion for stratigraphic horizon, lithology, and fluid prediction
(Peer reviewed; Journal article, 2020)We have developed an efficient methodology for Bayesian prediction of lithology and pore fluid, and layerbounding horizons, in which we include and use spatial geologic prior knowledge such as vertical ordering of ... 
Bayesian uncertainty quantification of perturbative QCD input to the neutronstar equation of state
(Peer reviewed; Journal article, 2023)The equation of state of neutronstar cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities. The constraining power of the QCD input ... 
Beamforming anvendt på tauet antenne
(Bachelor thesis, 2022)I denne bacheloroppgaven har jeg skrevet om en ny generasjon tauet antenne med fokus på signalbehandlingen. Til å begynne med gjør jeg kort rede for signalbehandling i historisk sammenheng, og legger så fram problemstillingen. ... 
Beregning av Homologigrupper og Eulertall
(Bachelor thesis, 2022)I matematikk er homologi en generell måte å assosiere en sekvens av algebraiske objekter, som abelske grupper eller moduler, med andre matematiske objekter som topologiske rom. Dette gir en måte å se forskjell på topologiske ... 
Beyond cuts in small signal scenarios: Enhanced sneutrino detectability using machine learning
(Peer reviewed; Journal article, 2023)We investigate enhancing the sensitivity of new physics searches at the LHC by machine learning in the case of background dominance and a high degree of overlap between the observables for signal and background. We use two ... 
Black hole spectroscopy in the next decade
(Peer reviewed; Journal article, 2020)Gravitational wave observations of the ringdown of the remnant black hole in a binary black hole coalescence provide a unique opportunity of confronting the black hole nohair theorem in general relativity with observational ... 
Bottomonium suppression at RHIC and LHC
(Peer reviewed; Journal article, 201902)The strong suppression of heavy quarkonia is a good indicator that one has generated a quarkgluon plasma (QGP) in an ultrarelativistic heavy ion collision. Recent advancements in first principles calculations of the heavy ... 
Bridgeland Stability Conditions and the Hilbert Scheme of Skew Lines in Projective Space
(PhD thesis UiS;, Doctoral thesis, 202303)Bridgeland stability conditions are powerful tools for studying derived categories, with several applications to algebraic geometry. They were introduced by Bridgeland in 2002 [Bri07], who was motivated by Douglas’ work ... 
Broad excitations in a 2+1D overoccupied gluon plasma
(Peer reviewed; Journal article, 202105)Motivated by the initial stages of highenergy heavyion collisions, we study excitations of farfromequilibrium 2+1 dimensional gauge theories using classicalstatistical lattice simulations. We evolve field perturbations ... 
Bryan’s Maximum Entropy Method—Diagnosis of a Flawed Argument and Its Remedy
(Peer reviewed; Journal article, 202009)The Maximum Entropy Method (MEM) is a popular data analysis technique based on Bayesian inference, which has found various applications in the research literature. While the MEM itself is wellgrounded in statistics, I ... 
Bubble nucleation and quantum initial conditions in classical statistical simulations
(Peer reviewed; Journal article, 2022)Classicalstatistical lattice simulations provide a useful approximation to outofequilibrium quantum field theory, but only for systems exhibiting large occupation numbers, and only for phenomena that are not intrinsically ... 
Can cancer cells inform us about the tumor microenvironment?
(Peer reviewed; Journal article, 2023)Characteristics of the tumor microenvironment (TME) such as the leaky intratumoral vascular network and the density and composition of the desmoplastic extracellular matrix (ECM) contain essential information that determine ...

Chiral density wave versus pion condensation at finite density and zero temperature
(Journal article; Peer reviewed, 201804)The quarkmeson model is often used as a lowenergy effective model for QCD to study the chiral transition at finite temperature T, baryon chemical potential μB, and isospin chemical potential μI. We determine the parameters ... 
Chiral soliton lattice in QCDlike theories
