Nonlinearly charged AdS black holes, extended phase space thermodynamics and Joule–Thomson expansion

We study thermodynamics and phase transitions of magnetically charged by nonlinear electrodynamics (NED) Anti-de Sitter (AdS) black holes in an extended space. The cosmological constant is treated as a thermodynamic pressure whereas the hole mass considered such chemical enthalpy. horizon shows analogy with Van der Walls liquid–gas system. define quantities which are conjugated to parameter NED magnetic charge. It shown that first law generalized Smarr relation hold. critical exponents same Waals Joule–Thomson adiabatic expansion NED-AdS investigated because behavior holes. coefficient, inversion isenthalpic curves discussed. minimum temperature corresponding event radius obtained.
