Regular AdS black holes holographic heat engines in a benchmarking scheme

Abstract

In this work, we explore some properties of holographic heat engines with Regular Anti-de Sitter black holes as the working substances in a benchmarking scheme. Namely, the Hayward, Bardeen and Maxwellian classes which are solutions of Einstein gravity coupled to a non-linear electromagnetic field. We also examine how the nonlinear electrodynamics parameter, the size of the benchmark circular cycle, and the charge of such black holes can influence the efficiency of the cycle. In the end, a cross-comparison of the efficiencies of different black hole heat engines suggests that the Hayward class is the more efficient one, and the constraint μ<1 also increases the efficiency and renders it more sensitive as the charge varies.
