| contents | Inspired by string theory topics, we investigate the Reissner Nordstrom AdS black holes in noncommutative spacetime with Lorentzian smeared distributions. Concretely, we study certain thermodynamic properties including the criticality behaviors by computing the relevant quantities. For large radius approximations, we first derive the asymptotic expansions of the mass and charge functions appearing in the metric function of such black holes. Then, we approach the thermodynamics in the extended phase space. After the stability discussion, we examine the P V criticality in noncommutative geometry by calculating the corresponding thermodynamic quantities. As a result, we show that the proposed black holes exhibit certain similarities with Van der Waals fluid systems. Finally, we present a discussion on the Joule Thomson expansion showing perfect universality results appearing in charged AdS black holes. |
