A Deep Dive into classical and Topological CFT Thermodynamics in Lifshitz and Hyperscaling Violating Black Holes
Mohammad Ali S. Afshar, Mohammad Reza Alipour, Saeed Noori Gashti +1
To effectively utilize the AdS/CFT correspondence, a precise set of rules must be established to guide the translation of computed quantities in the gravitational sector into their…
Assessing WGC Compatibility in ModMax Black Holes via Photon Spheres Analysis and WCCC Validation
Saeed Noori Gashti, Mohammad Ali S. Afshar, Mohammad Reza Alipour +3
It seems that the regime of Hawking radiation and evaporation ultimately drives charged black holes toward super-extremality of the charge parameter and the dominance of extremal c…

The discovery of Higgs mechanism within the context of spontaneous symmetry breaking has offered a new perspective on the early time cosmic inflation and also on the relationship b…
Cooling and heating regions of Joule-Thomson expansion for AdS black holes: Einstein-Maxwell-Power-Yang-Mills and Kerr Sen black holes
Mohammad Reza Alipour, Saeed Noori Gashti, Mohammad Ali S. Afshar +1
In this paper, we study the Joule-Thomson Expansion (JTE) process for two types of black holes: AdS-Einstein-Maxwell-Power-Yang-Mills (AEMPYM) and AdS-Kerr-Sen (AKS). Our study foc…
Thermodynamic topology of black holes from bulk-boundary, extended, and restricted phase space perspectives
