Glass-transition properties of Yukawa potentials: from charged point particles to hard spheres

Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Jun;89(6):063105. doi: 10.1103/PhysRevE.89.063105. Epub 2014 Jun 30.

Abstract

The glass transition is investigated in three dimensions for single and double Yukawa potentials for the full range of control parameters. For vanishing screening parameter, the limit of the one-component plasma is obtained; for large screening parameters and high coupling strengths, the glass-transition properties cross over to the hard-sphere system. Between the two limits, the entire transition diagram can be described by analytical functions. Unlike other potentials, the glass-transition and melting lines for Yukawa potentials are found to follow shifted but otherwise identical curves in control-parameter space.
