Noncommutative Phantom BTZ Black Hole (2503.03725v1)

Abstract: This work explores the thermodynamic and geometric properties of phantom BTZ black holes within the framework of noncommutative spacetime, where noncommutative effects are incorporated via Lorentzian distributions for mass and charge. The resulting modifications in spacetime geometry introduce significant alterations to horizon structures and curvature singularities. A comprehensive and comparative thermodynamic analysis is conducted, examining the differences between phantom and ordinary matter cases. This includes an investigation of Hawking temperature, entropy, heat capacity, and stability criteria. Additionally, the black hole is analyzed as a thermodynamic heat engine, with its efficiency evaluated as a function of noncommutative parameters. Our findings highlight the profound impact of noncommutativity on the thermodynamic behavior and efficiency of phantom BTZ black holes, revealing new insights into the interplay between quantum spacetime effects and exotic field dynamics. The results indicate that noncommutative corrections not only modify the stability conditions of these black holes but also play a crucial role in governing phase transitions. Furthermore, we demonstrate that noncommutativity influences energy extraction processes, refining our understanding of black hole thermodynamics in lower-dimensional spacetimes and distinguishing the behavior of phantom and ordinary matter cases.
