Phase diagrams of a nonlinear magnetic charged rotating AdS black hole with a quintessence field

Abstract

In this paper, we investigate the phase transitions and critical behavior of a nonlinear magnetically charged rotating AdS black hole, with a particular emphasis on the influence of a quintessence field. Our comprehensive thermodynamic analysis explores the impact of thermal fluctuations on the black hole's properties. We observe that for larger black holes, the corrected entropy remains positive, similar to the uncorrected case, which highlights the significant role of thermal fluctuations in modifying the entropy of smaller black holes. Through a meticulous analysis of various thermodynamic properties, we derive explicit analytical expressions for the critical points. Our findings demonstrate that the quintessence field significantly affects phase transitions, resulting in distinct critical phenomena. Notably, the black hole's phase transitions exhibit striking similarities to those observed in van der Waals fluids, offering deeper insights into the complex thermodynamic behavior of these systems across different scales.
