Since the pioneering work by Hawking, Carter, Bardeen and Page, Black hole thermodynamics is by now a rich and active area of research, which continues to enlighten our understanding of strong gravity and its relationship with quantum physics. In the context of AdS spacetimes, Hawking-Page phase transition has already shown the existence of deep physics connecting black holes and finite temperature CFTs. More recently, exciting developments are taking place due to the emergence of concrete relation between AdS black holes and van der Waals liquid-gas system, especially from the extended thermodynamic phase space (dynamical cosmological constant scenario) point of view. There have been exciting developments from AdS/CFT point of view, in a variety of topics involving Chaos, holographic complexity, black hole interior, Jackiw-Teitelboim gravity and with applications to condensed matter systems, such as SYK Models. Many novel approaches are being undertaken and continue to evolve at rapid pace currently, to probe the black hole phase transitions and consolidating the analogy with fluid systems, ranging from: the thermodynamics techniques via the localization of discontinuities of the heat capacity, analysis of thermodynamic geometry through Ruppeiner curvature, the AdS/CFT tools including entanglement entropy and two-point correlation function to study quasi-normal modes and many more. We aim to collect manuscripts that reflect the state of the art in black hole thermodynamic, with original contributions as well as review articles from leading experts in the topics to follow: • Black hole microstates and entropy • Information paradox and black hole evaporation • AdS/CFT interpretation of black hole phase transitions. • Geometrical thermodynamics • Entanglement entropy • Thermodynamics of black holes in various theories of gravity • Dynamical and thermal stabilities of black holes • Black hole remnants from thermodynamic point of view • Holographic complexity and chaos
