Matching Scherrer's k essence argument with alterations of Di Quark scalar fields permitting an eventual comological constant dominated inflationary expansion

TL;DR

This paper models universe nucleation and evolution using di quark scalar fields and k-essence, showing a transition from dark matter-energy mix to a cosmological constant-dominated universe consistent with observations.

Contribution

It introduces a novel scalar field model based on di quark pairs that aligns Scherrer's k-essence with cosmological phase transitions and universe nucleation.

Findings

Scalar field evolution matches observed cosmic acceleration.

Speed of sound reaches unity during phase transition.

Model supports universe nucleation via di quark scalar fields.

Abstract

We previously showed that we can use di quark pairs as a model of how nucleation of a new universe occurs. We now can construct a model showing evolution from a dark matter dark energy mix to a pure cosmological constant cosmology due to changes in the slope of the resulting scalar field,using much of Scherrer's k-essence model.This same construction permits a use of the speed of sound,in k-essence models evolving from zero to one. Having the sound speed eventually reach unity permits matching conventional cosmological observations in the aftermath of change of slope of a di quark pair generated scalar field during the nucleation process of a new universe. These results are consistent with applying Bunyi and Hu's semi classical criteria for cosmological potentials to indicate a phase transition alluded to by Dr. Edward Kolbs model of how the initial degrees of freedom declined from over 100 to something approaching what we see today in flat space cosmology.
