Non-minimally Coupled Cosmological Models with the Higgs-like Potentials and Negative Cosmological Constant

TL;DR

This paper investigates non-minimally coupled scalar field cosmologies with Higgs-like potentials and negative cosmological constant, revealing a transition from inflation to a cyclic universe with oscillating expansion rates.

Contribution

It introduces a novel analysis of cyclic cosmological behavior in models with Higgs-like potentials and negative cosmological constant, highlighting the oscillatory dynamics of the Hubble parameter.

Findings

The universe can undergo multiple cycles before collapsing.

Oscillations of the Hubble parameter depend on initial conditions.

Transition from inflation to cyclic behavior is demonstrated.

Abstract

We study dynamics of non-minimally coupled scalar field cosmological models with Higgs-like potentials and a negative cosmological constant. In these models the inflationary stage of the Universe evolution changes into a quasi-cyclic stage of the Universe evolution with oscillation behaviour of the Hubble parameter from positive to negative values. Depending on the initial conditions the Hubble parameter can perform either one or several cycles before to become negative forever.
