AdS Black Holes in the Framework of Nonlinear Electrodynamics, Thermodynamics, and Joule–Thomson Expansion

The thermodynamics and phase transitions of magnetic Anti-de Sitter black holes were studied. We considered extended-phase-space thermodynamics, with the cosmological constant being a thermodynamic pressure hole mass treated as chemical enthalpy. mimic behavior Van der Waals liquid. Quantities conjugated to coupling nonlinear electrodynamics (NED) charge are obtained. Thermodynamic critical points investigated. It was demonstrated that first law generalized Smarr relation hold. Joule–Thomson adiabatic expansion NED-AdS is dependence inversion temperature on minimum found.
