Fine micro-thermal structures for Reissner-Nordstr\"om black hole

Understand

We solve the condundrum on whether the molecules of the Reissner-Nordstr\"om black hole interact through the Ruppeiner thermodynamic geometry, basing our study on the concept of the black hole molecule proposed in [Phys.
