A new black hole coupled with nonlinear electrodynamics surrounded by quintessence: Thermodynamics, Geodesics, and Regge-Wheeler Potential

Abstract: We present a new exact solution to the gravitational field equations, where nonlinear electrodynamics (NLED) serves as the matter source in the presence of a quintessence field (QF). This solution describes a static, spherically symmetric black hole in the context of Anti-de Sitter (AdS) space, with the black hole (BH) surrounded by quintessence matter. The resulting black hole solution generalizes the AdS Schwarzschild-Kiselev black hole and reduces to the standard AdS-Schwarzschild black hole in the appropriate limits. Additionally, under certain conditions, this solution recovers the Bardeen-Kiselev regular black hole. We further explore the horizon structure and thermodynamic properties of this new black hole spacetime, accounting for the contributions from both NLED and the QF, including the state parameter of the QF. These contributions modify the spacetime geometry, thereby altering the thermodynamic behavior of the black hole. Moreover, we analyze the geodesic equations and show how NLED and the QF influence the effective potential for massless photon particles. Finally, we study the Regge-Wheeler (RW) potential for this regular black hole and demonstrate how variations in the parameters (NLED and QF) affect the RW potential for fields of different spins: spin-zero ($S=0$), spin-one ($S=1$), and spin-two ($S=2$). To illustrate the effects, we provide graphical representations of the RW potential for both multipole numbers $\ell=0$ and $\ell=1$.
