摘要：Gravity is believed to have a deep and inherent relation to thermodynamics. We study phase transitions and critical behaviors in the extended phase space of asymptotic anti-de Sitter black holes in Einstein-Horndeski gravity. We demonstrate that the black hole in Einstein-Horndeski gravity undergoes a phase transition and P - V criticality mimicking the van der Waals gas-liquid system. The key approach in our study is to introduce a more reasonable pressure instead of the previous pressure P = -Lambda/8 pi related to the cosmological constant Lambda, and this proper pressure is motivated by the asymptotical behavior of the black hole. Moreover, we also obtain P - V criticality in the two cases with Lambda = 0 and Lambda > 0 for the first time, which implies that the cosmological constant A may not be a necessary pressure candidate for black holes at the microscopic level. We present critical exponents for these phase transition processes.
