We investigate the adsorption of helium in alkali wedges at zero temperature within a fully unrestricted density-functional theory. We have found a sequence of shapes that includes one filling transition on the nonwettable Cs and one emptying transition for every alkali, as well as a threshold for metastable configurations where helium does not populate the wedge apex.

Abstract

We investigate the adsorption of helium in alkali wedges at zero temperature within a fully unrestricted density-functional theory. We have found a sequence of shapes that includes one filling transition on the nonwettable Cs and one emptying transition for every alkali, as well as a threshold for metastable configurations where helium does not populate the wedge apex.
