A shoulder in the radial distribution function, previously linked to crystalline ordering, appears even with attractive forces, not just high density packing. This finding challenges the exclusive association of this structural precursor to freezing with dense fluid packing effects.

Area of Science:

  • * Physics and Chemistry of Fluids
  • * Statistical Mechanics
  • * Materials Science

Background:

  • * Simulation studies highlight a shoulder in the radial distribution function (RDF) of hard spheres near freezing.
  • * This shoulder is often attributed to local crystalline ordering in dense fluids.
  • * The exact cause and universality of this structural feature remain subjects of investigation.

Purpose of the Study:

  • * To investigate the origin of the shoulder in the RDF of dense fluids.
  • * To determine if attractive interactions, not solely packing effects, influence this structural precursor to freezing.
  • * To utilize an advanced theoretical framework for accurate analysis of local packing constraints.

Main Methods:

  • * Application of an inhomogeneous integral equation theory.

  • * Modeling of systems with both hard-sphere repulsion and short-range attraction.
  • * Calculation of radial distribution functions across varying interaction strengths.

    • Main Results:

    • * The shoulder in the RDF was observed even when short-range attractive interactions were included.
    • * The inclusion of attraction broadened the fluid-solid coexistence region.
    • * The appearance of the shoulder correlated with this broadened coexistence region.

    Conclusions:

    • * The shoulder in the RDF is not exclusively a consequence of high-density packing effects in hard spheres.
    • * Attractive forces play a significant role in the formation of this structural feature.
    • * The findings provide a more nuanced understanding of the fluid-solid transition and local ordering.
