“…In this context, a great deal of interest has recently been devoted to the modified theories of gravity, such massive gravity [2,[22][23][24][25][26][27][28][29][30]. The latter theories spectrum show up a massive spin-2 graviton, providing an explanation of the accelerated expansion of the universe without invoking dark energy.…”

We apply the new thermodynamical method proposed initially by Hindi. et al [1] to revisit the phase structure of the AdS black hole in the massive gravity framework. In comparison to the standard thermodynamical method used in literature [2], we show that this new technical approach can easily reproduce the critical behavior inherent to this black hole configuration and addresses some of the shortcomings of the standard method. We also show the ability of this new perception to find all possible critical points and regions in which phase transitions occur, an impossible task in the standard method.

“…Subsequently, in order to better crossly compare the efficiency of the heat engines with different black holes as the working material, a circular cycle of the heat engine in the pressure-volume plane has been introduced as a benchmarking prescription by Chakraborty and Johnson [31]. After Johnson's pioneering work, the concept of heat engines has been generalized to other different black holes (for an incomplete list of references, see [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47]). Particularly, the properties of the holographic heat engine with accelerating AdS black holes as the working substance have drawn considerable interest.…”

Using a reasonable choice in normalizing the timelike Killing vector, we investigate the thermodynamic properties of charged accelerating Anti-de Sitter (AdS) black holes. We find that the expression of the thermodynamic mass in the first law of thermodynamics displays an inextricably intertwining behavior with the charge due to the unusual asymptotic structure of the accelerating black holes. Meanwhile, the thermodynamic length as a potential conjugate to the varying cosmic string tension is introduced and analyzed in detail, and the possible phase behavior of the charged accelerating black holes is also discussed in a standard thermodynamic analysis. Furthermore, we also investigate the properties of holographic heat engines with charged accelerating AdS black holes as the working substance in a benchmarking scheme. We find that the efficiencies of the black hole heat engines can be influenced by both the size of the benchmark circular cycle and the cosmic string tension. More interestingly, the existence of charge may significantly increase the efficiencies of the black hole heat engines and make them be more sensitive to a varying cosmic string tension. A cross-comparison of the efficiencies of different black hole heat engines suggests that the acceleration also increases the efficiency and renders it more sensitive as the charge varies.

“…Since our world is far from being ideal, so it is more realistic to study the heat engine defined via black holes with momentum relaxation. The engine efficiency modified by mass of graviton, which breaks the diffimophism system in the bulk and so introduces the momentum relaxation in the dual theory [23], has been carefully studied in [24,25]. One of us studied the heat engine in the Einstein-Maxwell-Axions theory [26], where the momentum relaxation is introduced by the linear massless axion fields [27].…”

We study the extended thermodynamical properties of the charged black hole in Horndeski model with the k-essence sector. Then we define a holographic heat engine via the black hole.We compute the engine efficiency in the large temperature limit and compare the results with the exact ones. With the given specified parameters in the rectangular engine, the higher order coupling suppresses the engine efficiencies.
