Primordial perturbations from polymer inflation
Seahra, Sanjeev (University of New Brunswick)

Inflationary perturbations provide a "Planck scale microscope" that allow us to access scales relevant to quantum gravity. One of the possible outcomes of the loop quantum gravity programme is that conventional Schrodinger quantization may be replaced by a fundamentally discrete algorithm at very small scales: namely, polymer quantization. In this talk, we determine the effects of polymer quantization on the spectrum of primordial perturbations, building on previous work that demonstrated how the polymer quantization of a massless scalar can drive inflation.
