Joule–Thomson expansion of Bardeen black hole with a cloud of strings

Abstract

This study focuses on the newly suggested Bardeen BH concept with a cloud of strings around it. Isenthalpic curves in the [Formula: see text] plane are explored concurrently with the investigation of the Joule–Thomson coefficient and inversion temperature. A comparison between the behavior of the BH and the Van der Waals fluid is made in order to shed light on the system and clarify its similarities and differences. A crucial component of our research entails determining corrected entropy in order to comprehend thermal fluctuations. Based on corrected entropy, the thermal stability debate shows that there is no fluctuation when it comes to small BHs. Additionally, we investigate the energy emission process from the Bardeen BH solution with a cloud of strings in order to clarify this important thermodynamic feature.
