3He impurities in 4He systems adsorbed on curved substrates

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...
