Resumo
The present work aims to analyze the quantum dynamics contained in the Planck era of the Universe, its emergence mechanism for the inflationary phase and its classical dynamics in a homogeneous and isotropic model, composed of a perfect fluid in the form of dust and a Chaplygin gas. The analysis was carried out through probabilistic calculations of quantum tunneling of a numerical model quantized by the Crank-Nicolson method, whose calculations were performed in terms of the model parameters. The results show a greater susceptibility for the classical emergence of a Universe filled with dust and Chaplygin gas, when compared to results found in the literature for a model in which the Universe is filled with Chaplygin gas and radiation.
