Nonequilibrium phase transitions and violent relaxation in the Hamiltonian mean-field model
Nonequilibrium phase transitions and violent relaxation in the Hamiltonian mean-field model
We discuss the nature of nonequilibrium phase transitions in the Hamiltonian mean-field model using detailed numerical simulations of the Vlasov equation and molecular dynamics. Starting from fixed magnetization water bag initial distributions and varying the energy, the states obtained after a violent relaxation undergo a phase transition from magnetized to …
