We investigate thermodynamics and geometrothermodynamics of regular Bardeen -AdS black hole with quintessence. The thermodynamics of the black hole is studied using temperature-entropy (T-S) and Pressure -Volume (P-V) plots, which indicate critical behavior. This is also confirmed from the divergence of specific heat against entropy, which shows a second order phase transition. Using the concept of thermodynamic Ruppeiner and Weinhold geometry, we calculated the thermodynamic curvature scalar RR and RW in the quintessence dark energy regime. While these curvature scalars enable us to identify the critical behavior, they do not show divergence at the phase transition points observed in specific heat study. To resolve this puzzle we have adopted the method of geometrothermodynamics proposed by Hernando Quevedo. Choosing a Legendre invariant Quevedo metric, the curvature scalar RQ shows singularity at the same point as seen in the specific heat divergence.

“…Phase transitions in black holes surrounded by quintessence are widely studied. Thermodynamics of Reissner-Nordström and regular black holes surrounded by quintessence were investigated in [77][78][79][80][81][82][83]. Thermodynamic geometry and geometrothermodynanics for different regular black holes were studied in [65].…”

“…Furthermore, more regular black hole models have been established, and the related physical properties have been widely studied. [38][39][40][41][42][43][44][45][46][47][48][49]. Therefore, it is necessary to study the influence of the relevant state parameters on the shadow image and observation characteristics in the Bardeen black hole.…”

By exploring the photon motion in the region near the Bardeen black hole, the shadow and luminosity of the black hole surrounded by different accretions are studied in this paper. We analyzed the changes in shadow imaging and observation luminosity when the relevant physical parameters are changed. In the static and infalling spherical accretion, although the radius of the shadow and the position of the photon spheres do not change in the two models, the observation intensity of the black hole with infalling accretion is significantly lower than that of the static accretion. In particular, in the case of the thin disk accretion, we study the contribution of the photon rings, lensing rings and direct emission to the total observed flux. The result shows that the observed brightness of black holes is mainly determined by direct emission. Furthermore, in the different forms of the emission modes, the lensing ring will provide a small part of the observation flux, while the photon ring can provide a negligible observation flux. After that, we compare our results with the Schwarzschild black hole, we find that the existence or change of the parameter g will greatly affect the imaging and observation intensity of black hole shadow. Hence, the parameter g change the spacetime structure which affects the photon sphere, the deflection angle and the observations of black hole shadows.

“…Wei and Liu [29] discussed a relation between phase transition and null geodesics of charged AdS BH. Saleh et al [30] examined thermodynamics as well as phase transition of Bardeen BH surrounded by quintessence and found that presence of quintessence induces phase transition in considered BH. Kuang et al [31] evaluated thermal quantities of AdS non-linear electrodynamic BH.…”

This paper investigates thermodynamics, quasi-normal modes, thermal fluctuations and phase transitions of Reissner-Nordström black hole with the effects of non-linear electrodynamics. We first compute the expressions for Hawking temperature, entropy and heat capacity of this black hole and then obtain a relation between Davies's point and quasi-normal modes with non-linear electrodynamics. We also observe the effects of logarithmic corrections on uncorrected thermodynamic quantities such as entropy, Hawking temperature, Helmholtz free energy, internal energy, Gibbs free energy, enthalpy and heat capacity. It is found that presence of non-linear electrodynamic parameter induces more instability in black holes of large radii. Finally, we analyze the phase transitions of Hawking temperature as well as heat capacity in terms of entropy for different values of charge (q), horizon radius (r + ) and coupling parameter (α). We obtain that Hawking temperature changes its phase from positive to negative for increasing values of q and r + while it shows opposite trend for higher values of α. The heat capacity changes its phase from negative to positive for large values of charge, horizon radius and coupling parameter.
