"Surface term for the capillary condensations transitions in a slit geometry"
I. Urrutia and L. Szybisz
Phys. Rev. B 74(17) (2006) 172510/1-4
It is shown that a bare simple fluid model (SFM) proposed some years ago for studying adsorption between two semi-infinite solid walls can be improved by modifying the surface term in the grand potential for the film phase. Such a correction substantially improves the agreement between the predictions for phase transitions provided by that SFM and results obtained from calculations carried out for 4He with the density-functional method at zero temperature. The corrective term depends on the strength of the adsorption potential and observables of bulk helium.
