Equilibrium state of a classical fluid of hard rods in an external field

  • J. K. Percus


The external field required to produce a given density pattern is obtained explicitly for a classical fluid of hard rods. All direct correlation functions are shown to be of finite range in all pairs of variables. The one-sided factors of the pair direct correlation are also found to be of finite range.

Key words

One-dimensional fluid hard rods nonuniform direct correlation function
