The P-V phase transition of the FRW universe
European Physical Journal C: Particles and Fields, 2022 We define thermodynamic pressure P by work density W as the conjugate quantity of thermodynamic volume V from field equation. We derive the equations of state P=P(V, T) for the Friedmann–Robertson–Walker (FRW) universe in Einstein gravity and a modified ...
