The dark matter freeze out and beyond
(Master thesis, 2022)Evidence of the existence of dark matter has been found due to deviations of gravitational motion of astronomical objects. We want to investigate the dark matter topic, which is constantly evolving due to the fast development ... -
The Fourier transform and its applications to partial differential equations.
(Master thesis, 2021)In this master’s thesis I will introduce a way to solve partial differential equations and boundary value problems by transforming signals from a time domain to a frequency domain, and back. This algorithm is ... -
The reasons for the collapse of the Tacoma Narrows Bridge and the lessons for the classroom
(Bachelor thesis, 2022)On 7 November 1940, a historical event occurred for suspension bridge construction and aerodynamic engineering around suspension bridges. Engineers investigating the event concluded the bridge collapsed due to high winds ... -
The Unicity of a Blow-down.
(Master thesis, 2023)In algebraic geometry, projective varieties are classified up to isomorphism. This involves classifying the varieties up to birational equivalence and classifying nonsingular varieties in each equivalence class up to ... -
Thermalization and dynamical spectral properties in the quark-meson model
(Peer reviewed; Journal article, 2020-07)We investigate the nonequilibrium evolution of the quark-meson model using two-particle irreducible effective action techniques. Our numerical simulations, which include the full dynamics of the order parameter of chiral ... -
Thermalization of non-Abelian gauge theories at next-to-leading order
(Peer reviewed; Journal article, 2022)We provide the first next-to-leading-order (NLO) weak-coupling description of the thermalization process of far-from-equilibrium systems in non-Abelian gauge theory. We study isotropic systems starting from either over- ... -
Thermalization of weakly coupled non-Abelian plasmas at next-to-leading order
(Peer reviewed; Journal article, 2023)We employ the QCD kinetic theory, including next-to-leading(NLO) order corrections in coupling constant, to study the evolution of weakly coupled non-Abelian plasmas towards thermal equilibrium. For two characteristic ... -
Thermodynamics of antiferromagnetic solids in magnetic fields
(Peer reviewed; Journal article, 2020)We analyze the thermodynamic properties of antiferromagnetic solids subjected to a combination of mutually orthogonal uniform magnetic and staggered fields. Low- temperature series for the pressure, order parameter and ... -
Thermopower in an anisotropic two-dimensional Weyl semimetal
(Journal article, 2020-01)We investigate the generation of an electric current from a temperature gradient in a two-dimensional Weyl semimetal with anisotropy in both the presence and absence of a quantizing magnetic field. We show that the anisotropy ... -
Thoughts about the utility of perturbative QCD in the cores of neutron stars – contribution to a roundtable discussion on neutron stars and QCD
(Peer reviewed; Journal article, 2022)In this contribution, I discuss the utility that perturbative QCD offers in studying the matter in the cores of neutron stars. I discuss the reasons why perturbative QCD can constrain the equation of state at densities far ... -
Tidserier for finansiell data
(Bachelor thesis, 2023)The motivation for this thesis is to grasp general theory and principles for modeling time series, for the application to financial data. By going through the theory that makes up this field and bringing that perception ... -
Topological G2 and Spin(7) strings at 1-loop from double complexes
(Peer reviewed; Journal article, 2022)We study the topological G2 and Spin(7) strings at 1-loop. We define new double complexes for supersymmetric NSNS backgrounds of string theory using generalised geometry. The 1-loop partition function then has a target-space ... -
Towards Bayesian Estimation of Compartmental Models for COVID-19
(Master thesis, 2021)This thesis explores concept of compartmental modelling of infectious disease particularly like COVID-19. The world is still under siege by COVID-19. I have discussed two such fundamental mathematical models SIR and SEIR ... -
Towards dielectric relaxation at a single molecule scale
(Peer reviewed; Journal article, 2022)Dielectric relaxation lies at the heart of well-established techniques of dielectric spectroscopy essential to diverse fields of research and technology. We report an experimental route for increasing the sensitivity of ... -
Towards learning optimized kernels for complex Langevin
(Peer reviewed; Journal article, 2023)We present a novel strategy aimed at restoring correct convergence in complex Langevin simulations. The central idea is to incorporate system-specific prior knowledge into the simulations, in order to circumvent the NP-hard ... -
Towards the nucleon hadronic tensor from lattice QCD
(Peer reviewed; Journal article, 2020-06)We present the first calculation of the hadronic tensor on the lattice for the nucleon. The hadronic tensor can be used to extract structure functions in deep inelastic scatterings and to provide information for neutrino-nucleon ... -
Transmission in pseudospin-1 and pseudospin-3/2 semimetals with linear dispersion through scalar and vector potential barriers
(Peer reviewed; Journal article, 2020-09)We investigate the tunneling of pseudospin-1 and pseudospin-3/2 quasiparticles through a barrier consisting of both electrostatic and vector potentials, existing uniformly in a finite region along the transmission axis. ... -
Transport Properties of Superfluid Phonons in Neutron Stars
(Peer reviewed; Journal article, 2021-03)We review the effective field theory associated with the superfluid phonons that we use for the study of transport properties in the core of superfluid neutrons stars in their low temperature regime. We then discuss the ... -
Transversality, Intersection Theory and Sheaf Theory
