| Summary: | We study the thermodynamics of AdS4 black hole solutions of Einstein-Maxwell
theory that are accelerating, rotating, and carry electric and magnetic charges.
We focus on the class for which the black hole horizon is a spindle and can be
uplifted on regular Sasaki-Einstein spaces to give solutions of D = 11 supergravity that are free from conical singularities. We use holography to calculate the
Euclidean on-shell action and to define a set of conserved charges which give
rise to a first law. We identify a complex locus of supersymmetric and nonextremal solutions, defined through an analytic continuation of the parameters,
upon which we obtain a simple expression for the on-shell action. A Legendre
transform of this action combined with a reality constraint then leads to the
Bekenstein-Hawking entropy for the class of supersymmetric and extremal black
holes. |
