TL;DRAbstract

We qantize the linearly polarized Gowdv ?3 model with a mmsless scalar field by applying a hvbrid qrran- tization that combinm Loop Quantum Cosrnology and Fock qumtizations.This nodel llows us to modelize flt Fyiedmann-Robertrcn-Walker cosrnologie lilled with irrhornogeneities, rroviding a perfect wenmio to study the quiltum back-rerotion of iuhomogeneitis on a loop quarrtizc<l hornogenous arxl isotropic backgrouud.
