Generalized effective description of loop quantum cosmology

Understand

The effective description of loop quantum cosmology (LQC) has proved to be a convenient platform to study phenomenological implications of the quantum bounce that resolves the classical big-bang singularity.

• Originally, this description was derived using Gaussian quantum states with small dispersions.
• In this paper we present a generalization to incorporate states with large dispersions.
• Specifically, we derive the \emph{generalized} effective Friedmann and Raychaudhuri equations and propose a generalized effective Hamiltonian which are being used in an ongoing study of the phenomenological consequences of a broad class of quantum geometries.
