Traversability of quantum improved wormhole solution

TL;DR

This paper explores the traversability of quantum-improved wormholes, demonstrating that pseudospherical ones can be traversable with non-exotic matter, unlike spherical wormholes, within a specific quantum gravity model.

Contribution

It introduces a quantum improvement approach to wormhole analysis showing the potential for traversability without exotic matter in pseudospherical cases.

Findings

Pseudospherical wormholes can be traversable with non-exotic matter.

Spherical wormholes remain non-traversable under the same conditions.

Quantum improvement influences wormhole traversability properties.

Abstract

We have investigated the problem of traversability of wormholes in the framework of quantum improvement of gravity theory arising from functional renormalization group methods to describe the asymptotic safe quantum gravity. We have shown that improved pseudospherical wormholes could be traversable with non--exotic matter, while spherical ones could not. This is done within a specific model of improvement.
