Researchers explore microscopic structures of black holes through lens of thermodynamics

By Josh Perry, Editor


A recent study by researchers by Nankai University explored the microscopic structures of black holes from the perspective of thermodynamics to better understand their properties, according to a report that was released by Science China Press and published on Phys.org.

According to the report, scientists have determined that black holes have temperature and entropy and undergo phase transitions under certain circumstances.


Originally, scientists used string theory and fuzzball theory to explore the microscopic structures of black holes, but the Chinese researchers turned to Ruppeiner’s thermodynamic geometry method to study the thermally-stable SAdS black hole.


“The molecular potential of a thermal stable SAdS black hole is proposed for the first time,” the report explained. “In addition, based on the proposed molecular potential description, the thermo-correction to the equation of state for thermally stable SAdS black holes is calculated, and the rationality of the correction term is analyzed.”


The research was recently published in Science China: Physics, Mechanics and Astronomy. The abstract stated:


“The microscopic structure of black holes remains a challenging subject. In this paper, based on the well-accepted fact that black holes can be mapped to thermodynamic systems, we make a preliminary exploration of the microscopic structure of the thermodynamically stable Schwarzschild anti-de-Sitter (SAdS) black hole.


“In accordance with the number density and thermodynamic scalar curvature, we give the interaction potential among the molecules of thermodynamically stable SAdS black holes and analyze its effectiveness.


“Moreover, we derive the thermo-correction to the equation of state for such black holes that arises from interactions among black-hole molecules using virial coefficients.”
