报告摘要：

Thermodynamic geometry can be constructed analogue to the Riemannian geometry. Via the corresponding scalar curvature, the microscopic properties of the system can be revealed. In this talk, we shall introduce a special kind geometry, Ruppeiner geometry. The interpretation and empirical summaries of the geometry will be given. At first, we shall apply it to the Van der Waals fluid system. Combining with the liquid-gas phase transition, the microscopic properties between the fluid molecules will be examined. At the critical point, the critical phenomena of the scalar curvature will be investigated. Then, we shall construct the Ruppeiner geometry for the black hole systems. For the black hole systems, the critical phenomena of the scalar curvature can also be observed. In particular, we can test black hole microstructures by employing the Ruppeiner geometry. The properties of the black hole microstructures are uncovered. Therefore, such approach can provide an alternative way to examine the microstructures of black hole. This shall shed new light on the nature of black holes.
