Hayward black hole heat engine efficiency in anti-de Sitter space

In this paper, we attempt to further study the heat engine efficiency for regular black hole (BH) with an anti-de Sitter (AdS) background where working material is Hayward–AdS (HAdS) BH. extended phase space, investigate of HAdS BH by defining cosmological constant as thermodynamic pressure P and deriving mechanical work from PdV terms. Then, obtain relation between entropy/pressure plot these function figures. Meanwhile, compare that Bardeen–AdS (BAdS) BH, it found increases increase in magnetic charge q contrast BAdS decrease q. We more efficient than guess related structure.
