Creation of particles in a cyclic universe driven by loop quantum cosmology

Understand

We consider an isotropic and homogeneous universe in loop quantum cosmology.

• We assume that the matter content of the universe is dominated by dust matter in early time and a phantom matter at late time which constitutes the dark energy component.
• The quantum gravity modifications to the Friedmann equation in this model indicate that the classical big bang singularity and the future big rip singularity are resolved and are replaced by quantum bounce.
• It turns out that the big bounce and recollapse in the herein model contribute to a cyclic scenario for the universe.
