The Casimir effect for a cavity in the presence of compactified universal extra dimension

TL;DR

This paper investigates how the presence of a compactified universal extra dimension modifies the Casimir effect in a rectangular cavity, deriving new expressions for energy and force corrections.

Contribution

It provides a detailed derivation of the Casimir energy and force in the context of extra dimensions, highlighting the corrections introduced by the universal extra dimension.

Findings

Extra-dimension corrections to Casimir energy and force are quantified.

The nature of the Casimir force is affected by the presence of the extra dimension.

Explicit expressions for the Casimir energy in cavities with equal edges are derived.

Abstract

We reexamine the Casimir effect for the rectangular cavity with two or three equal edges in the presence of compactified universal extra dimension. We derive the expressions for the Casimir energy and discuss the nature of Casimir force. We show the extra-dimension corrections to the standard Casimir effect.
