Description
Lattice QCD calculations show that there is an analytic crossover from hadron resonance matter to a deconfined quark gluon plasma at vanishing baryon chemical potential. Many models predict that this analytic crossover changes to a line of first order phase transition at finite baryon chemical potential with a critical point. Due to the Fermi sign problem, we cannot have the lattice calculations at finite chemical potential, which is why there are several models that try to find the critical point. Here, we are trying to have an extrapolation in positive chemical potential by looking at contours of baryon density, which near the phase transition should overlap on each other and give us the spinodal region. Firstly, we will be working on Van der Waals model in both canonical and grand canonical ensemble and look how this extrapolation works and give us the phase transition and then project on to the QCD phase diagram.
