“…Next, as we will show, unlike the braneworld model with Einstein-Hilbert action [21], the Friedmann equation resulting from a model that contains the L 3 will be able to go back to the conventional four dimensional Friedmann equation, even with zero brane tension. Thus we set σ = 0 in our definition of brane matter action (11). In short, we consider the following action…”

“…The Horndeski theory is built up from four Lagrangian (L i , i = 2, 3, 4, 5). By appropriately choosing the parameters in each Lagrangian, well known specific scalar-tensor Lagrangian can be recovered, such as quintessence [7], k-essence [8], nonminimal derivative coupling (NMDC) [9,10,11,12,13], etc. are all contained in Horndeski theory.…”

A five dimensional braneworld cosmological model in general scalar-tensor action comprises of various Horndeski Lagrangian is considered. The Friedmann equations in the case of the strongly and weakly coupled L5 Horndeski Lagrangian have been obtained. The strongly coupled L5 model produces the Cardassian term ρ n with n = ±1/2, which can served as alternative explanation for the accelerated expansion phase of the universe. Furthermore, the latest combined observational facts from BAO, CMB, SNIa, fσ 8 , and H0 value observation suggest that the n = −1/2 term lies quite close to the constrained value. On the other hand, the weakly coupled L5 case has several new correction terms which are omitted in the braneworld Einstein-Hilbert model, e.g. the cubic ρ 3 and the dark radiation-matter interaction term χa −4 ρ. Furthermore, this model provides a cosmological constant constructed from the bulk scalar field, requires no brane tension, and supports the big bang nucleosynthesis (BBN) constraint naturally.

We discussed a mechanism that allows the universe to start from lower dimension (d < 4) in its very early era and evolves to four dimension at the end of the process. The mechanism is generated by a nonminimal derivative coupling of scalar field, where derivative terms of the scalar field coupled to curvature tensor. We solve the Einstein equations for a limit of large and nearly constant Hubble parameter and analyze the evolution of the Hubble parameter in this limit. The lower-dimensionality in early universe has advantages in the context of unification theory.Physics of early universe has attracted much attention. One of the main issue is the number of dimensions of the early universe, which is strongly related to the unification of all physical theories. String theory, as a candidate for the unification theory of physics, suggests that the universe consists of 26 (for bosonic string) and 10 dimensions (for superstring). As the universe evolves, the extradimensions compactified to a very small size, too small to be observabed. The idea of compactified extra dimensions then developed into braneworld model of gravity. In braneworld model, our four dimensional spacetime is embedded in five dimensional bulk and the matter field is constrained in the brane while the graviton can move freely in the bulk. One of the most popular model of braneworld scenario is the Randall-Sundrum model [1,2].Another candidate of unified theory of all physical phenomena is the quantum gravity. This theory has a good mathematical consistency in 1+1 and 1+2 dimensions, but not in 1+3 dimension ([3], and reference therein), which is the number of observable dimensions. Some attempts has been done to extend the theory to 1+3 dimensions. There is a model proposed in [4] can be used to solve 1 arXiv:1407.6624v1 [physics.gen-ph]

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...
