From Symmetries to Scattering Amplitudes: A Lie-algebraic categorisation of symmetry-breaking patterns that create enhanced soft limits for NG bosons
(PhD thesis UiS;, Doctoral thesis, 2022-11)The standard calculation of scattering amplitudes in quantum field theory is carried out using a perturbative expansion, that at successive orders contains an escalating number of terms to calculate. The amplitudes depend ... -
Non-equilibrium quantum field dynamics in the early Universe
(PhD thesis UiS;, Doctoral thesis, 2023)Inflation is the leading paradigm of early Universe cosmology. It provides compelling explanations of the observed near-homogeneity of the cosmic microwave background (CMB) radiation, the spatial flatness of the Universe ...
