Structure and Thermodynamics of Solutions of Colloids interacting through Yukawa or Lu- Marlow Potentials using Computer Simulation

K. Elhasnaoui, A. Maarouf

Abstract


In this article, we used an expression described by Lu and Marlow, which
takes into account the finite size of the particles. To test this potential, we have
calculated the structure factor. As a method, we use the variational method
based on the Gibbs-Bogoliubov inequality. The resulting theoretical structure
factors obtained are found to be in a good agreement with the experimental
data of Grüner and Lehmann, which justified the interest in introducing such
a potential.
Keywords: Computer simulations, colloids, pair potential, structure factor,
Structure, Thermodynamics variational method.
