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.
Condensation of helium in wedges

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.File in questo prodotto:
