Phase transitions, geometrothermodynamics and critical exponents of black holes with conformal anomaly

Understand

We investigate the phase transitions of black holes with conformal anomaly in canonical ensemble from different perspectives.

• Some interesting and novel phase transition phenomena have been discovered.
• Firstly, we discuss the behavior of the specific heat and the inverse of the isothermal compressibility.
• It is shown that there are striking differences in Hawking temperature and phase structure between black holes with conformal anomaly and those without it.
