Joule-Thomson Expansion of Reissner-Nordstrom AdS Black Holes in $f(R)$ gravity

Abstract

In this paper, we study Joule-Thomson expansion for charged AdS black holes in \(f(R)\) gravity. We obtain the inversiontemperatures as well as inversion curves, and investigate similarities and differences between van der Waals fluidsand charged AdS black holes in \(f(R)\) gravity for this expansion.In addition, we determine the position of the inversion point versus different values ofthe mass \(M\), the charge \(Q\) and the parameter \(b\) for such black hole. At this point, the Joule-Thomson coefficient \(\mu\) vanishes, an import feature that we used to obtain the cooling-heating regions by scrutinizing the sign of the \(\mu\) quantity.
