Tricritical quantum point and inflationary cosmology

TL;DR

This paper explores how a quantum tricritical point influences holographic protection in inflationary cosmology, leading to a topology change that prevents entropy bound saturation during the universe's early phase.

Contribution

It introduces a novel connection between quantum tricritical points and inflationary cosmology, highlighting a phase transition that affects holographic entropy bounds.

Findings

Transition from closed spacetime to de Sitter space due to quantum tricriticality

Topology change in early universe prevents entropy bound saturation

Holographic protection linked to phase transition in cosmological model

Abstract

The holographic protection due to inflationary cosmology is a conse- quence of a quantum tricritical point. In this scenario a closed spacetime solution transitions into an inflationary de Sitter spacetime. Saturation of the holographic entropy bound is prevented by the phase change in the topology of the early universe.
