Abstract:
It is shown that 3He impurities in sufficiently large 4He systems adsorbed onto substrates with curved geometries form surface bound states, analogous to the Andreev state on a planar liquid-vapor interface. We report the analysis performed for superfluid 4He adsorbed on the external surface of the nano-fullerene C60 and on cylindrical nano-wires of Au. It is found that a single 3He impurity diluted into such adsorbed structures behaves as on films on planar substrates and as on pure 4He clusters. © 2005 Springer Science+Business Media, Inc.
