Thermodynamic phase transition and Joule Thomson adiabatic expansion for dS/AdS Bardeen Black Holes with consistent 4D Gauss-Bonnet gravity

Abstract

In this letter we study thermodynamics of 4D AdS Bardeen Gauss-Bonnet (BGB) black hole. We show it can be involved in the process of the Joule-Thomson expansion. This is done by studying its inversion temperatures. Same as ordinary thermodynamics systems this black hole predicts cooling/heating phase transition if Joule-Thomson coefficient vanishes. Here we investigate effects of the black hole characteristics such as the magnetic charge, the mass and the GB coupling constant variations on the inversion temperature and the phase transition.

“…Kerr-AdS black holes [47], regular(Bardeen)-AdS black holes [48], RN-AdS black holes in f (R) gravity [49], quintessence RN-AdS black holes [50], Bardeen-AdS black holes [51] and other black holes [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71]. In these papers, the inversion curves, the isenthalpic curves and the heating-cooling regions in the T −P plane for different black holes were given.…”
