TL;DR
This paper demonstrates that gravitational entropy can be attributed to spacetimes with Misner strings, extending the understanding of gravitational thermodynamics beyond traditional horizons, based on stress-energy evaluations inspired by AdS/CFT.
Contribution
It introduces a novel approach to assign entropy to Misner strings in spacetimes without event horizons, expanding the scope of gravitational thermodynamics.
Findings
Gravitational entropy can be associated with Misner strings.
The approach is motivated by AdS/CFT correspondence.
Entropy assignment applies even without traditional horizons.
Abstract
I show that gravitational entropy can be ascribed to spacetimes containing Misner strings (the gravitational analogues of Dirac strings), even in the absence of any other event horizon (or bolt) structures. This result follows from an extension of proposals for evaluating the stress-energy of a gravitational system which are motivated by the AdS/CFT correspondence.
