Field Theoretic Models of Liquids
As an alternative to viewing a liquid explicitly a disordered collection of particles, molecular configurations can be described in terms of single particle fields such as the density. This lecture considers this alternative perspective — how the spatial analog of harmonic oscillator models leads to integral equations (e.g., PY, RISM, ...), and how manageable non-linear treatments have led to an understanding of freezing. Nevertheless, puzzling questions remain concerning symmetry breaking and the formation of glasses.
