Abstract
We report results of diffusion Monte Carlo calculations for both He absorbed in a narrow single walled carbon nanotube (R = 3.42 \AA) and strictly one dimensional He. Inside the tube, the binding energy of liquid He is approximately three times larger than on planar graphite. At low linear densities, He in a nanotube is an experimental realization of a one-dimensional quantum fluid. However, when the density increases the structural and energetic properties of both systems differ. At high density, a quasi-continuous liquid-solid phase transition is observed in both cases.
