Abstract

Motivated by loop quantum gravity, we propose two polymer quantization schemes for propagating modes of gravitational degrees of freedom and obtain the effective equations of such waves on quantum spacetime. We then derive the effects of the polymer parameters on the observables and show that (i) the amplitude of the waves will be modified, (ii) the speed of the waves receives pol ...
