“…Quintessence model is a model of a scalar field that governs the pressure of our universe to be negative then makes the accelerated expansion [36]. The study involving the scalar field in some frame of modified gravity theories in a cosmological scale can be discovered in [37,38,39,40,41,42,43,44,45]. The existence of quintessence possibly causes the change of the structure of some locally astrophysical manifestations of it such as black holes.…”

We present a new twisted rotating black hole solution by performing Demiański-Newman-Janis algorithm to the electrically and dyonically charged black hole with quintessence in Rastall theory of gravity. Using our black hole solution, we argue that Rastall gravity is not equivalent with Einstein gravity. For further explanation, the black hole properties such as the horizon and ergosphere are studied for which there are some different properties for those theories. Some thermodynamic properties of the black hole solution are also discussed. At the end, considering the Kerr/CFT correspondence is valid for our black hole solution, the central charge from the CFT of this extremal solution is derived. spacetime. It is considered a non-minimal coupling of the matter field to space-time geometry with the coupling constant κλ or Rastall parameter. This quantity quantifies the deviation from the Einstein theory of gravity. When Rastall parameter vanishes, it produces the Einstein theory of gravity. Furthermore, in [3,4] it is argued that Rastall gravity is a special case of f (R, T ) gravity.Rastall theory of gravity might be interpreted as a direct accomplishment of the Mach principle which suggests that the inertial properties of a mass distribution are determined by the distribution of mass-energy in the external space-time [5]. Thus, the source of gravitation, either mass-density or the elements of energy-momentum tensor, depends on the gravitational tensor. We can find also some recent research work that use this gravitational theory to explain the cosmological aspects such as the accelerating expansion of the universe and the inflationary problems [6,7,8,9,10,11,12,13,14,15,16]. In the smaller scale, some astrophysical configurations are investigated by performing this theory. For instance, the investigation of perfect fluid spheres, compact stars, neutron stars, black holes, and wormholes is done in the context of Rastall gravity [17,18,19,20,21,22,23,24,25]. Corresponding to black hole solutions in Rastall gravity, a fascinating non-commutative inspired black hole solution is obtained in [26]. In addition, the black hole solution with the source of a Gaussian matter distribution is obtained in [27]. Several extensions of black hole solution in Rastall gravity are further investigated in [28,29,30,31,32]. Besides that, the thermodynamic properties of black hole solutions in the Rastall gravity are discussed in [33].Recently, it is claimed by Visser [34] that Rastall theory of gravity is equivalent with Einstein theory. However, Darabi et al. [35] compare these two gravitational theories and summarize that Visser's conclusion is not correct. The argument in [35], indeed, supports Rastall theory of gravity for which this theory is still an open theory comparing to the usual general relativity. Henceforth, this theory may face the challenges of cosmological observations as the general relativity.In recent years, it is found that our universe experiences accelerated expansion due to the existence of dark energy that fi...

“…A model that is quite simple and can explain this phenomenon is quintessence [1]. This quintessence model is fine enough to describe dark energy even though many other models are proposed to be able to produce data that corresponds to an accelerated expanding universe such as in [2,3,4,5,6,7,8,9,10].…”

Rotating black hole solution surrounded by quintessential matter is recently discussed because it might be the promising solution to study the effect of dark energy in small scale of the universe. This quintessential solution is originally derived from the condition of additivity and linearity for the energymomentum tensor. We carry out the thermodynamic properties of this solution using the Kerr/CFT correspondence for several specific quintessential equation of state parameters. A problem arises when we compute the central charge because the canonical conserved charge is needed to be calculated from the Lagrangian. However, the exact Lagrangian of the quintessence is not defined yet in the original derivation. Yet we solve this problem by the assumption that there is only a contribution from gravitational field to the central charge. Then we could find the entropy of this black hole after calculating the temperature and using Cardy entropy formula. Another problem comes out when the spin goes to zero to find the Reissner-Nordström-NUT-Quintessence solution. To solve it, we extend to the 5-dimensional solution. In the end, we obtain the entropy for this 5-dimensional solution. So the quintessential black hole solution is dual with the CFT.
