Thermodynamic Volume of Kerr-bolt-AdS Spacetime

Understand

In theories of gravity where the cosmological constant defines a thermodynamic variable, the pressure, it has been shown that solutions of Einstein's equations have a corresponding thermodynamic volume.

• In general, the expression for the volume is not the same as the one arising from naive geometrical considerations.
• Both rotation and nut charge are properties known in the literature to give non-geometric thermodynamic volumes, and so we combine the two in a single example and compute the volume for the Kerr-bolt-AdS spacetime, presenting a new expression that generalizes the previously known non-geometric cases.
