We start from black hole thermodynamics, and associate cosmology constant with pressure. Then we add the pressure term into the first law of black hole thermodynamics, to discuss some properties about black hole phase transition. We use the Ruppeiner geometry, which is analogous to the Riemannian geometry to study black hole thermodynamics by treating temperature, volume and charge as parameters. We regard the probability of one state evolving to another state as the distance between two points. Longer distance represents smaller probability, and shorter distance represents bigger probability of transition between two states. It was pointed out that the scalar curvature divergent points are the same as the spinodal points of thermodynamics. Moreover, the sign of scalar curvature is also related to whether the interaction on the microstructure is a repulsive force or attractive force. This thesis will
review the phenomena that previous researchers had discussed with temperature and volume as thermodynamic variables. Later, we study the charged RN-AdS black holes, considering
the situation that black holes can exchange charge with outside. We derive the metric tensor, calculate the scalar curvature, and finally discuss the difference between the case in which black holes exchange charge or not with outside. |
