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.

Work in progress (not yet published). Includes computing the Casimir energy with its regularization, simplifying approximations proposed for that calculation, and building a program for the non-perturbative evolution of the universe.
