The high-density regime of kinetic-dominated loop quantum cosmology

Understand

We study the dynamics of states perturbatively expanded about a harmonic system of loop quantum cosmology, exhibiting a bounce.

• In particular, the evolution equations for the first and second order moments of the system are analyzed.
• These moments back-react on the trajectories of the expectation values of the state and hence alter the energy density at the bounce.
• This analysis is performed for isotropic loop quantum cosmology coupled to a scalar field with a small but non-zero constant potential, hence in a regime in which the kinetic energy of matter dominates.
