How to build a heat engine between two black holes:Starting from the 2023 CPhO problems
The theoretical fifth problem in the final round of the 2023 Chinese Physics Olympiad(CPhO)in-volves black hole thermodynamics.In this paper,we provide an introduction to the background of black hole ther-modynamics and further analyze the characteristics of thermodynamic cycles between black holes based on our re-search experience.Finally,we summarize some recent research progress in the field of finite system thermodynamics and statistical physics relevant to this topic.
