He4 adsorbed inside (10,10) single-walled carbon nanotubes
Diffusion Monte Carlo calculations on the adsorption of He4 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 He4 atoms are adsorbed close to the tube wall and a high-density arrangement charac...

| Sumario: | Diffusion Monte Carlo calculations on the adsorption of He4 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 He4 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. |
