Spectral function for overoccupied gluodynamics from classical lattice simulations
(Peer reviewed; Journal article, 2019)We study the spectral properties of an overoccupied gluonic system far from equilibrium. Using classical Yang–Mills simulations and linear response theory, we determine the statistical and spectral functions. We measure ... -
Gauged Wess-Zumino terms for a general coset space
(Peer reviewed; Journal article, 2019)The low-energy physics of systems with spontaneously broken continuous symmetry is dominated by the ensuing Nambu-Goldstone bosons. It has been known for half a century how to construct invariant Lagrangian densities for ... -
Exploits, advances, and challenges benefiting beyond Li-ion battery technologies
(Peer reviewed; Journal article, 2019)The battery market is undergoing quick expansion owing to the urgent demand for mobile devices, electric vehicles and energy storage systems, convoying the current energy transition. Beyond Li-ion batteries are of high ... -
Effective kinetic description of event-by-event pre-equilibrium dynamics in high-energy heavy-ion collisions
(Peer reviewed; Journal article, 2019)We develop a macroscopic description of the space-time evolution of the energy-momentum tensor during the pre-equilibrium stage of a high-energy heavy-ion collision. Based on a weak coupling effective kinetic description ... -
Real-time quantum dynamics, path integrals and the method of thimbles
(Peer reviewed; Journal article, 2019)Direct numerical evaluation of the real-time path integral has a well-known sign problem that makes convergence exponentially slow. One promising remedy is to use Picard-Lefschetz theory to flow the domain of the field ... -
Flow in AA and pA as an interplay of fluid-like and non-fluid like excitations
(Peer reviewed; Journal article, 2019)To study the microscopic structure of quark–gluon plasma, data from hadronic collisions must be confronted with models that go beyond fluid dynamics. Here, we study a simple kinetic theory model that encompasses fluid ... -
Spontaneous momentum dissipation and coexistence of phases in holographic Horndeski theory
(Peer reviewed; Journal article, 2019)We discuss the possible phases dual to the AdS hairy black holes in Horndeski theory. In the probe limit breaking the translational invariance, we study the conductivity and we find a nontrivial structure indicating a ... -
Realistic in-medium heavy-quark potential from high statistics lattice QCD simulations
(Peer reviewed; Journal article, 2019)We present our first results on a direct computation of the complex in-medium heavy quark potential from realistic lattice QCD simulations. Ensembles with Nτ = 12 from the HotQCD and TUMQCD collaboration offer unprecedented ... -
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 ... -
Multimessenger Constraints for Ultradense Matter
(Peer reviewed; Journal article, 2022)Recent rapid progress in neutron-star (NS) observations offers great potential to constrain the properties of strongly interacting matter under the most extreme conditions. In order to fully exploit the current observational ... -
Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Peer reviewed; Journal article, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
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 ... -
Some factors affecting the grades of technology students
(Peer reviewed; Journal article, 2017)In this study factors that affect the grades of Norwegian technology students have been investigated. The total data set contained 355.706 individual exams from 63 different engineering master programs during the 2010 to ... -
Science AMA Series: Ask the Society of Environmental Toxicology and Chemistry (SETAC) anything about Pharmaceuticals in the environment!
(Journal article, 2017)The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Pharmaceuticals in the environment: Potential ... -
Static quark-antiquark interactions at nonzero temperature from lattice QCD
