Helium in Nanoconfinement: Interplay Between Geometry and Wetting Behavior

This paper reviews the most recent research of adsorption of finite helium systems, performed in the frame of Density Functional theory. These comprehend the deposition and spreading of helium droplets on flat alkali metal surfaces, the determination of isotherms, the construction of the phase diagram of helium on such substrates, the adsorption of helium on spherical and cylindrical surfaces, the filling of wedges and of infinite polygonal pores, and the adsorption on planar surfaces structured with an array of parabolic nanocavities
