While the function is in general form, once reduced, the model can be transformed into some of the other well-known gravitation theories. After deriving the corresponding field equations and considering the flat Friedmann-Robertson-Walker type universe which is filled with ordinary cosmic matter, we discuss both the non-equilibrium and equilibrium profiles of galactic thermodynamics. We find that there exists an equilibrium picture of thermodynamics. Additionally, we also generalize ordinary f(T, phi, X) model's action to the case in which there exists an interaction between the chameleon and scalar fields.eninfo:eu-repo/semantics/closedAccessTeleparallel TheoryDark EnergyModified GravityThermodynamicsArticle3133WOS:0003860486000032-s2.0-8498924904110.1142/S0217732316501856Q2Q3
