The Dzugutov potential is typically implemented to model metallic glass-formers. It is also used to model a dodecagonal quasicrystal, which the Dzugutov system forms from the melt under certain conditions. The functional form of the potential is
Here is the Heaviside function defined as
Typically, the set of parameters A=5.82, B=1.280, a=1.87, b=1.94, c=1.10, d=0.27, and m=16 are used.
