Abstract

This paper investigates some implications of mimetic gravity on the black hole thermodynamics. We begin with an analysis of the mimetic action and its relationship to the spacetime curvature, highlighting the field equations and their contributions to the black hole solutions. Then we explore the behavior of various thermodynamic parameters including pressure, temperature and heat capacity, revealing some intriguing features of the system near the event horizon. We analyze also the inversion temperatures, inversion curves and the Joule–Thomson coefficients to enrich our comprehension of thermodynamic phenomena in this context. By extending coordinates close to the event horizon, we study the Joule–Thomson expansion, demonstrating how strong gravitational fields create pressure gradients similar to gas cooling processes. Comparison between mimetic black hole and Schwarzschild black hole in this setup provides a deeper understanding of the unique characteristics of the mimetic gravity.
