Abstract
Using molecular dynamics techniques, properties of the supercooled amorphous state have been studied for the soft-core model. By examining the temperature dependence of the pair distribution function, velocity autocorrelation function and self-diffusion constant for each quenched system, a glass transition is predicted separating supercooled liquid from a rigid amorphous solid. Below the glass transition temperature the structures are less temperature dependent than above the temperature. It is noted that no significant change on the temperature dependence, has been observed in the previous results of thermodynamic properties. The obtained pair distribution functions in the glassy state are successfully compared with those of some metallic glasses.Keywords
