ABSTRACT
The phase transition of the antiferromagnetic-torsional XY model is studied with molecular dynamics.
In the process of releasing energy, we find a minimally stable state. The minimally stable state indicates the process of disordered state to ordered state when the 2nd phase transition was derived.
The temperature of phase transition for the iferromagnetic-torsional XY model is lower than that for the antiferromagnetic XY model.
A increase of the coefficient J2 will delay the temperature of phase transition for the antiferromagnetic-torsional XY model .
