Quantum virial expansion approach to thermodynamics of ${}^4$He adsorbates in carbon nanotube materials: Interacting Bose gas in one dimension

Abstract

I demonstrate that ${}^4$He adsorbates in carbon nanotube materials can be treated as one-dimensional interacting gas of spinless bosons for temperatures below 8 K and for coverages such that all the adsorbates are in the groove positions of the carbon nanotube bundles. The effects of adsorbate-adsorbate interactions are studied within the scheme of virial expansion approach. The theoretical predictions for the specific heat of the interacting adsorbed gas are given.
