In the Hamiltonian Mean-Field model, quasi-stationary states are often observed, and they are represented as stable stationary solutions to the Vlasov equation. Changing values of parameters of the system, for instance, total energy, dynamical phase transitions of magnetization occur. The dynamical phase transitions are 1st, 2nd and 3rd order depending on the parameters what we change. On a two dimensional parameter space, we show the 1st order curve and the 2nd order curve collapsed at a tricritical point.
