Can Holographic dark energy increase the mass of the wormhole?

TL;DR

This paper investigates how different holographic dark energy models affect the mass of Morris-Thorne wormholes during cosmic evolution, revealing mass decrease in quintessence and increase in phantom phases.

Contribution

It introduces a detailed analysis of wormhole mass evolution under three holographic dark energy models using both scale factor and Hubble parameter reconstructions.

Findings

Wormhole mass decreases during quintessence phase.

Wormhole mass increases during phantom phase.

Mass behavior depends on dark energy parameterization.

Abstract

In this work, we have studied accretion of dark energy (DE) onto Morris- Thorne wormhole with three different forms, namely, holographic dark energy, holographic Ricci dark energy and modified holographic Ricci dark energy . Considering the scale factor in power-law form we have observed that as the holographic dark energy accretes onto wormhole, the mass of the wormhole is decreasing. In the next phase we considered three parameterization schemes that are able to get hold of quintessence as well as phantom phases. Without any choice of scale factor we reconstructed Hubble parameter from conservation equation and dark energy densities and subsequently got the mass of the wormhole separately for accretion of the three dark energy candidates. It was observed that if these dark energies accrete onto the wormhole, then for quintessence stage, wormhole mass decreases up to a certain finite value and then again increases to aggressively during phantom phase of the universe.
