Holographic thermalization and gravitational collapse in the spacetime dominated by quintessence dark energy

TL;DR

This paper investigates how quintessence dark energy influences holographic thermalization by analyzing gravitational collapse and thermalization probes, revealing that lower state parameters hinder plasma thermalization.

Contribution

It introduces a holographic model of gravitational collapse in a quintessence-dominated spacetime and examines the impact of the dark energy's state parameter on thermalization processes.

Findings

Lower quintessence state parameters slow down thermalization.

Thermalization velocity decreases with smaller state parameters.

Results provide insights into the role of dark energy in holographic thermalization.

Abstract

In this paper, the thermalization has been studied holographically. Explicitly in the gravity side, we consider the gravitational collapse of a thin shell of dust in a spacetime dominated by quintessence dark energy. With the thermalization probes such as the normalized geodesic length and minimal area surface, we study the effect of the state parameter for the quintessence dark energy on the thermalization. Our results show that the smaller the state parameter of quintessence is, the harder the plasma to thermalize. We also investigate the thermalization velocity and thermalization acceleration. We hope our results here can shed light on the nature of the quintessence dark energy.
