Thermodynamics in f(R,T) theory of gravity
Open accessAbstract
A non-equilibrium picture of thermodynamics is discussed at the apparent horizon of FRW universe in f ( R , T ) gravity, where R is the Ricci scalar and T is the trace of the energy-momentum tensor. We take two forms of the energy-momentum tensor of dark components and demonstrate that equilibrium description of thermodynamics is not achievable in both cases. We check the validity of the first and second law of thermodynamics in this scenario. It is shown that the Friedmann equations can be expressed in the form of first law of thermodynamics T h dS ′ h + T h d 𝚥 S ′ = − dE ′+ W ′ dV , where d 𝚥 S ′ is the entropy production term. Finally, we conclude that the second law of thermodynamics holds both in phantom and non-phantom phases.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
