4D static solutions with interacting phantom fields

TL;DR

This paper explores three static models involving two interacting phantom and ghost scalar fields, demonstrating numerically that regular solutions can be found for traversable wormholes, brane-like structures, and spherically symmetric configurations.

Contribution

It introduces three new static models with interacting phantom and ghost scalar fields and shows the existence of regular solutions through numerical analysis.

Findings

Regular solutions exist for all three models.

Numerical methods confirm the stability of solutions.

Models include traversable wormholes, brane-like, and spherical configurations.

Abstract

Three static models with two interacting phantom and ghost scalar fields were considered: a model of a traversable wormhole, a brane-like model and a spherically symmetric problem. It was shown numerically that regular solutions exist for all three cases.
