Improved regularization from Quantum Reduced Loop Gravity

Understand

The choice of the regularization scheme in Loop Quantum Cosmology (LQC) is crucial for the predicted phenomenology.

• We outline how the improved scheme can be naturally realized in Quantum Reduced Loop Gravity, describing the Universe as an ensemble of microstates labeled by different graphs.
• The new effective dynamics presents corrections to LQC, which do not significantly affect the bouncing scenario for the most relevant kinds of matter fields in cosmology $(w \leq 1)$.
