4He adsorbed inside (10,10) single walled carbon nanotubes

Abstract

Diffusion Monte Carlo calculations on the adsorption of ${}^4$He in open-ended single walled (10,10) nanotubes are presented. We have found a first order phase transition separating a low density liquid phase in which all ${}^4$He atoms are adsorbed close to the tube wall and a high density arrangement characterized by two helium concentric layers. The energy correction due to the presence of neighboring tubes in a bundle has also been calculated, finding it negligible in the density range considered.
