Joule-Thomson expansion for quantum corrected AdS-Reissner-Nordstrom black holes in Kiselev spacetime

arXiv:2105.04689 · doi:10.1103/PhysRevD.107.024045

Abstract

In this work we study the inversion temperature associated with the Joule-Thomson expansion from the thermodynamics of AdS-Reissner-Nördstrom black holes. We include quantum corrections in a cosmological fluid that can describe phantom dark matter or quintessence, both in a Kiselev scenario. The description of such physical systems involves numerical solutions and the results are presented as temperature-pressure plots for various values of the parameters of our model. We find non-zero minimum inversion temperatures as well as non-zero minimum pressures depending on the values of those parameters. Completing our study, we also find isenthalpic curves associated with black hole fixed mass processes.

V2: 18 pages, 7 figures. In this version, we included a discussion of the First Law and a deduction of equations with a non-zero pressure even at zero inversion temperature that explain our (unchanged) numerical results. This version matches the published one in PRD
