摘要：
The promotion of crystal phase transitions in molecular dynamics (MD) simulations was realized by controlling the momentum of the MD cell. It was implemented by increasing the mass or velocity of the MD cell instantaneously during simulations within the framework of the constant-pressure method by Parrinello and Rahman. This method induced phase transitions in benzene crystals which have not been obtained in conventional MD simulations. This method is useful for the global search of stable (and metastable) crystal structures.
