"Liquid-drop-like model for cylindrical helium systems"
L. Szybisz
Physica A 283(1-2) (2000) 193-197
Free liquid 4He at T = 0 K with cylindrical symmetry is studied. The ground-state energy and chemical potential are computed by using a density functional approach. A liquid-drop-like model is formulated for analyzing the behavior of these observables as a function of the size of the systems. It is shown that such a model allows to get precise information about the asymptotic values of the energy per particle and surface tension.
