P-V CRITICALITY AND STABILITY ANALYSIS OF CHARGED BTZ BLACK HOLES

This work explores the thermodynamic properties of charged BTZ black holes in a (2+1)-dimensional extended phase space framework. By analyzing temperature pressure relationships and heat capacity as functions of the event horizon radius, we identify critical points and examine Gibbs free energy to confirm stability. Our findings reveal significant similarities between charged BTZ black holes and other black hole solutions, enhancing our understanding of their thermodynamic behavior. This work contributes to theoretical physics and cosmology by uncovering complex interactions and providing insights into quantum gravity theories, while laying a foundation for future research in higher-dimensional systems.
