Joule-Thomson expansion in AdS black holes with momentum relaxation

Abstract

The inner structure of realistic materials make them exhibit momentum relaxation. In this paper we study the holographic version of the Joule-Thomson effect on AdS black holes in which translational invariance is broken by two methods: First by considering planar black holes in general relativity supported by axion scalar fields with a linear dependence on the horizon coordinates and secondly by considering black holes in massive gravity models in which momentum relaxation is obtained by breaking the bulk diffeomorphism invariance of the theory. In contrast with black holes studied so far, for both theories it is possible to obtain inversion curves with two branches reproducing the behavior of Van der Wall fluids. Moreover in the specific case of the massive gravity model we show that black holes can heat up when crossing the inversion curve.

“…JT expansion is used as a isoenthalpic tool to show the thermal expansion where there is heating and cooling regimes. Note that the pressure decreases for the expanding thermal system with a temperature T so that the inversion temperature is obtained where the JT coefficient vanishes and at the inversion temperature T i , and corresponding inversion pressure P i , there is a cooling and heating transition [95][96][97][98].…”

“…By considering the cosmological constant The sign of the Joule-Thomson coefficient plays an essential role in the research process, which can be used to determine whether heating or cooling will occur.

“…In general, there is only one inversion curve corresponding to the black hole system, because a black hole system usually does not have high and low inversion temperatures. However, in the study of Joule-Thomson expansion in AdS black holes with momentum relaxation by Cisterna and Hu [18], they obtained a high and low inversion curve similar to the van der Waals fluid system. Now we consider Joule-Thomson expansion of BI-AdS Black Hole in 4D EGB gravity.…”
