Effects of additional sources on Casimir Wormholes

TL;DR

This paper investigates how adding different physical fields and effects to the Casimir energy influences the properties of wormholes, particularly their size and traversability, without destroying their fundamental structure.

Contribution

It introduces an auxiliary stress tensor approach to analyze the impact of electromagnetic, thermal, and scalar fields on Casimir wormholes, revealing their compatibility with traversability.

Findings

Additional fields do not compromise wormhole traversability.

Thermal effects modify the energy density but preserve wormhole structure.

Extra sources influence the size of the wormhole throat.

Abstract

In this contribution we explore the consequences of including additional sources to the original Casimir energy Stress-Energy Tensor. In particular, we will discuss the effects of an additional electromagnetic field, the modification induced by non-zero temperature effects on the energy density obtained by a Casimir device and finally the effect obtained by including a massless scalar field. For each of these examples, we have introduced an auxiliary stress tensor which we have interpreted as a thermal tensor. Consequences on the size of the throat are also discussed. We will show that these additional extra fields do not destroy the traversability of the wormhole.
