| contents | In this paper, we derive exact black hole solutions within the framework of fourth-order quasitopological gravity (4QTG) coupled to power-law Maxwell electrodynamics in five-dimensional spacetimes. We explore the thermodynamic properties of these solutions, including entropy, temperature, and electric potential, and verify the validity of the first law of thermodynamics. Our analysis spans asymptotically anti-de Sitter (AdS), de Sitter (dS), and flat spacetimes, revealing that thermal stability is exclusively achievable in asymptotically AdS black holes, while dS and flat solutions exhibit universal instability. The study highlights the unique role of higher-curvature terms in modifying black hole thermodynamics and horizon structures, providing new insights into the interplay between geometry, thermodynamics, and quantum gravity via the AdS/CFT correspondence. Furthermore, we demonstrate that 4QTG supports multi-horizon black holes even in the absence of charge, a feature absent in Einstein gravity. These findings underscore the importance of higher-curvature corrections in resolving classical limitations of general relativity and offer new avenues for exploring quantum gravity and holographic duality. |
