Abstract
In this research paper, we investigate the structure of the horizon and ergosphere of a rotating ModMax black hole. The motion of test particles is analyzed by studying the characteristics of the innermost stable circular orbit (ISCO) and the behavior of the effective potential. Different values of the screening factor and the charge of the rotating ModMax black hole are explored in this study. Moreover, we also examine several thermodynamic quantities such as Enthalpy, Hawking temperature, Gibbs free energy, and entropy of the black hole. Additionally, the center-of-mass-energy (CM) generated by the collision of two particles (both in extremal and non-extremal cases) is briefly investigated for specific parameter values associated with this black hole.
