Chameleon Cosmology Model Describing the Phantom Divide Line Crossing
F. Cannata, A.Yu. Kamenshchik
TL;DR
This paper presents an exact solution in Chameleon cosmology that models the universe's evolution from a Big Bang to a Rip, including crossing the phantom divide line, using two scalar field functions.
Contribution
It introduces a novel exact solution in Chameleon cosmology that captures complex universe evolution and phantom divide crossing with two scalar functions.
Findings
Exact solution for Bang-to-Rip evolution
Model includes crossing of the phantom divide line
Utilizes two independent scalar field functions
Abstract
An exact solution describing the evolution of the type Bang-to-Rip with the phantom divide line crossing is constructed in the Chameleon cosmology model, based on two independent functions of the scalar field.
