Catalytic Creation of Bubble Universe Induced by Quintessence in Five Dimensions

TL;DR

This paper explores how quintessence in five-dimensional spacetime can catalyze bubble nucleation, leading to a universe with potential implications for inflation and dark energy, while considering theoretical constraints like the trans-Planckian censorship conjecture.

Contribution

It introduces a novel model of bubble universe creation via quintessence in five dimensions, linking it to inflation and dark energy origins.

Findings

Decay of metastable Minkowski vacuum to anti-de Sitter vacuum analyzed

Constraints on model parameters imposed by trans-Planckian censorship conjecture

Proposed mechanism for inflation and dark energy in higher-dimensional quintessence context

Abstract

We investigate the bubble nucleation in five dimensional spacetime catalyzed by quintessence. We especially focus on decay of a metastable Minkowski vacuum to an anti-de Sitter vacuum and study dynamics of the bubble on which four dimensional expanding universe is realized. We also discuss the trans-Planckian censorship conjecture and impose a constraint on the parameter space of the catalysis. As an application of this model, we propose an inflation mechanism and an origin of the dark energy in the context of quintessence in five dimensions.
