research Imprints of Cosmic Topology in the Primordial Power Spectrum Computing Casimir energy (including regularization) and the non-perturbative evolution of the universe, looking for imprints of non-trivial cosmic topology in the primordial power spectrum. Vacua and Non-Trivial Topology Classical-regime simulations showing that a "cosmic egg" solution is possible when a scalar field is added to the Casimir energy. EDE with Alpha-Attractors A simulation pipeline from inflation to today, searching for an alpha-attractors model that explains inflation, the Hubble tension, and observed dark energy.
