Superoscillatory initial states during inflation: theory, CMB constraints, and prospects for galaxy clustering
Ali Nayeri
We construct an explicit boundary-action realization of superoscillatory initial states (SIS) for inflation, in which quantum interference within a band-limited initial wavefunctio…

Inflationary branch decoherence and the cosmological arrow of time
Ali Nayeri
We analyze branch decoherence in inflationary quantum cosmology by computing reduced density matrices and branch-overlap factors for long-wavelength perturbations. The Hartle-Hawki…
