Phenomenological implications of an alternative Hamiltonian constraint for quantum cosmology

TL;DR

This paper explores a simplified Hamiltonian constraint in loop quantum cosmology derived from a symmetry-reduced self-dual Plebanski action, analyzing its phenomenological implications and comparing with standard models.

Contribution

It introduces a new, explicitly quantizable Hamiltonian constraint from a symmetry-reduced self-dual Plebanski action in loop quantum cosmology.

Findings

The model yields distinct semi-classical phenomenological predictions.

Comparison shows differences with standard Loop Quantum Cosmology results.

Abstract

In this paper we review a model based on loop quantum cosmology that arises from a symmetry reduction of the self dual Plebanski action. In this formulation the symmetry reduction leads to a very simple Hamiltonian constraint that can be quantized explicitly in the framework of loop quantum cosmology. We investigate the phenomenological implications of this model in the semi-classical regime and compare those with the known results of the standard Loop Quantum Cosmology.
