The Thermodynamic Properties of Warped Taub-NUT AdS Black String

Abstract: When we consider five-dimensional warped Taub-NUT/Bolt AdS black string with minimally coupled massive scalar field, we calculate entropy by using the brick wall method. It is found that they are proportional to being quadratically divergent in a cutoff parameter. In particular, we show that the entropy of warped Taub-NUT AdS black string holds for an area law in the bulk as well as on the brane. Furthermore, when the negative cosmological constant is treated as thermodynamic pressure, we calculate the thermodynamic quantities and investigate their extended thermodynamic properties. Interestingly, we obtain a thermodynamically stable range as a function of the temperature for warped Taub-NUT AdS black string. Finally, we also study a proportional behavior of the thermodynamic quantities along a warp factor, and find that an entropy, a specific heat, a Gibbs free energy, and an action difference increase as a warp factor grows up.
