Density functional study of two-dimensional He clusters
نویسندگان
چکیده
Binding energies and density profiles of two-dimensional systems of liquid He with different geometries are studied by means of a zero-range density functional adjusted to reproduce the line tension obtained in a previous diffusion Monte Carlo calculation DMC=0.121 K/Å . It is shown that this density functional provides accurate results for the binding energy of large clusters with a reasonable computational effort.
