We used field-theoretic simulations to study the equilibrium behavior of a polymer solution
under good solvent conditions confined to a slit of width L. In particular, we obtained the
chemical potential and the density profiles across the slit for different values of the monomer
excluded volume over a wide range of concentrations C. We also obtained mean field
results for the chemical potential and the density profiles. The effective correlation length ξ
eff was calculated from the density profiles and compared to the mean field result (valid in …
