Particle Physics and Dark Energy: Beyond Classical Dynamics

摘要: In this work, quantum corrections to classical equations of motion are investigated for dynamical models dark energy featuring a time-evolving quintessence scalar field. Employing effective field theory, the robustness tracker potentials against as well their impact on cosmological observables discussed. Furthermore, it is demonstrated that rolling can also play an important role baryogenesis in early universe. The macroscopic time-evolution fields be described from first principles within nonequilibrium theory based Kadanoff-Baym derived 2PI action. A framework nonperturbative renormalization provided. Renormalized proposed and finiteness shown special case.
