The adsorption potential is computed by means of a technique denoted as the elementary source method. We analyze a rhombic pore with Cs walls, where we show the existence of multiple interfacial configurations at some linear densities, which correspond to metastable states. Shape transitions and hysterectic loops appear in patterns which are richer and more complex than in a cylindrical tube with the same transverse area.4 p.application/pdfeng(c) The American Physical Society, 2008Teoria del funcional de densitatAdsorcióHeliNanoestructuresDensity functional theoryAdsorptionHeliumNanostructuresHelium in polygonal nanopores at zero temperature: Density functional theory calculationsinfo:eu-repo/semantics/article558461info:eu-repo/semantics/openAccess
