Stability Aspects of Wormholes in $R^2$ Gravity

TL;DR

This paper examines the stability of wormholes in $R^2$ gravity by analyzing radial perturbations and explores particle orbits and tidal effects for infalling observers.

Contribution

It provides a novel stability analysis of wormholes specifically within $R^2$ gravity, including perturbation methods and orbital dynamics.

Findings

Identification of stable and unstable regions for wormholes in $R^2$ gravity

Characterization of particle orbits around the wormhole

Assessment of tidal forces experienced by infalling observers

Abstract

We study radial perturbations of a wormhole in $R^2$ gravity to determine regions of stability. We also investigate massive and massless particle orbits and tidal forces in this space-time for a radially infalling observer.
