Polymer cosmology with polymer matter: effective dynamics

We study the effective dynamics of a polymer quantized scalar field living on an effective polymer quantized homogeneous and isotropic background. We use a presureless dust field as an internal clock, and work with volume variables. Our results show how the quantum bounce in the early universe is affected as the initial conditions and various physical parameters — including the scalar field polymer scale — are varied. We also find, generically, that there is asymmetric evolution across the bounce.
