Description
Quantum geometric modifications to general relativistic dynamics have successfully resulted in the resolution of various cosmological singularities in loop quantized models. The polymer nature of gravity in these models dictates the evolution in the Planck regime, replacing big bang by a (swift) big bounce. But studies so far treat matter on an unequal footing by considering it only in the Schrodinger representation or unpolymerized. We show that if the matter is also polymerized, it dictates singularity resolution and changes the Planck scale physics as understood in loop quantum cosmology in a significant way. We discuss some phenomenological consequences of this model in particular implications for the inflationary paradigm.
