Query: Entanglement growth during Van der Waals like phase transition   We address the problem of describing the coexistence state of two different
black holes and Van der Waals like phase transition in Reissner-Nordstr\"om-AdS
space-time. We start by a small charged black hole, then introduce a collapsing
neutral thin-shell described by Vaidya metric to form a large one. The
formation of the large black hole does not change the temperature and free
energy of the initial state. We discuss the entanglement growing during the
phase transition. The transition is always continuous and the saturation time
is determined by the final state. It opens a possibility for studying the
holography from excited states to excited states.
