Observational assessment of the viability of de Sitter Gödel de Sitter phase transition

de Sitter–Gödel–de Sitter phase transition (dGd) is a possible geometrical phase transition in the very early universe. It induces fluctuations with possibly observable traces on matter and radiation fields. Here we present a simulation based on dGd to investigate possible perturbations which could...
