Ab initio study: Investigating the adsorption behaviors of polarized greenhouse gas molecules on pillar[5]arenes
(Peer reviewed; Journal article, 2023)Supramolecular organic frameworks (SOFs) based on Pillar[5]arenes (P[5]A) have shown great potential in capturing and separating greenhouse gases. In this study, we investigate the adsorption behaviors of other environmentally ... -
An Introduction to Supersymmetry
(Masteroppgave/UIS-TN-IMF/2019;, Master thesis, 2019-06-14)This thesis gives an introduction to supersymmetry. We compute the Poincaré- conformal- and Clifford algebra in any dimension. Most examples are in four dimensions, including the Wess-Zumino model and supersymmetric gauge ... -
Analyticity in Several Complex Variables
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020)there are many similarities between complex analysis in several variables and one variable but there are also some important differences between holomorphic functions of a single variable and holomorphic functions of $n$ ... -
Anomalous low-temperature thermodynamics of QCD in strong magnetic fields
(Journal article; Peer reviewed, 2017-11)The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ... -
Atomic scattering factors and atomic cross-sections in x-ray crystallography
(Masteroppgave/UIS-TN-IMF/2018;, Master thesis, 2018-06-15)Crystallographers as well as other scientists and engineers need reliable sets of physical data. Focus is here set upon the x-ray attenuation coefficients (the atomic photoeffect cross-section, and the incoherent (Compton) ... -
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 ... -
Bottomonium suppression at RHIC and LHC
(Peer reviewed; Journal article, 2019-02)The strong suppression of heavy quarkonia is a good indicator that one has generated a quark-gluon plasma (QGP) in an ultrarelativistic heavy ion collision. Recent advancements in first principles calculations of the heavy ... -
Broad excitations in a 2+1D overoccupied gluon plasma
(Peer reviewed; Journal article, 2021-05)Motivated by the initial stages of high-energy heavy-ion collisions, we study excitations of far-from-equilibrium 2+1 dimensional gauge theories using classical-statistical lattice simulations. We evolve field perturbations ... -
Charged FENE-P non-newtonian fluid model

Chiral density wave versus pion condensation at finite density and zero temperature
(Journal article; Peer reviewed, 2018-04)The quark-meson model is often used as a low-energy 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 phase in warm QCD
(Peer reviewed; Journal article, 2021-11)We analyze the phase diagram of quantum chromodynamics at low-to-moderate temperature, baryon chemical potential and external magnetic field within chiral perturbation theory at next-to-leading order of the derivative ... -
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 ... -
Correlated insulators in twisted bilayer graphene
