Casimir energy in multiply connected static hyperbolic Universes

TL;DR

This paper extends the calculation of Casimir energy to a broader class of static hyperbolic universes with complex topologies, exploring how topology influences quantum vacuum effects.

Contribution

It generalizes previous results to include multiple static hyperbolic universes with nontrivial topologies, broadening understanding of Casimir energy in these models.

Findings

Casimir energy depends on the topology of the universe.

Explicit calculations for various hyperbolic manifolds.

Insights into quantum effects in nontrivial topologies.

Abstract

We generalize a previously obtained result, for the case of a few other static hyperbolic universes with manifolds of nontrivial topology as spatial sections.
