Thermodynamical properties of an ideal gas in a traversable wormhole

In this work, we analyze the thermodynamic properties of non-interacting particles under influence of the gravitational field of a traversable wormhole. In particular, we investigate how the thermodynamic quantities are affected by the Ellis wormhole geometry, considering three different regions to our study: asymptotically far, close to the throat, and at the throat. The thermodynamic quantities turn out to depend strongly on parameter that controls the wormhole throat radius. By varying it, there exist an expressive modification in the thermodynamic state quantities, exhibiting both usual matter and dark energy-like behaviors. Finally, the interactions are regarded to the energy density and it seems to indicate that it cures the dark energy-like features.

Automated summary

This work analyzes the thermodynamic properties of non-interacting particles under the influence of the gravitational field of a traversable wormhole. The study investigates how the thermodynamic quantities are affected by the Ellis wormhole geometry in three different regions. The results show that the thermodynamic state quantities exhibit significant changes by varying the parameter controlling the wormhole throat radius, displaying behaviors similar to both usual matter and dark energy. Additionally, the interactions seem to have the potential to cure the dark energy-like features.
