thermodynamics and thermal stability of btz-modmax black holes

Motivated by a new interesting nonlinear electrodynamics (nled) model known as modification maxwell (modmax) theory, we obtain an exact analytic btz black hole solution in the presence of a new nled model and the cosmological constant. afterward, by considering the obtained solution, we hawking temperature, entropy, electric charge, mass, and electric potential. we extract the first law of thermodynamics for the btz-modmax black hole. we study thermal stability by evaluating the heat capacity (local stability) and helmholtz free energy (global stability). by comparing the local and global stabilities, we find the common areas that simultaneously satisfy the local and global stabilities
