Condensed phases of gases inside nanotube bundles
An overview is presented of the various phases predicted to occur when gases are absorbed within a bundle of carbon nanotubes. The behavior may be characterized by an effective dimensionality, which depends on the species and the temperature. Small molecules are strongly attracted to the interstitial channels between tubes. There, they undergo transitions between ordered and disordered quasi-on...
متن کاملThe saddle-point method for condensed Bose gases
The application of the conventional saddle-point approximation to condensed Bose gases is thwarted by the approach of the saddle-point to the groundstate singularity of the grand canonical partition function. We develop and test a variant of the saddle-point method which takes proper care of this complication, and provides accurate, flexible, and computationally efficient access to both canonic...
متن کاملThe Interaction of Rare Gases with Metals
Interaction potentialsof rare gases withmetal surfaces are calculated and compared with experimental data. A local dielectric function formalism and the density functional method are used in the calculation of the attractive and repulsive energies respectively. Depth and curvature variations of the potentials suggest a classification into light (He, Ne) and heavy rare gases. Sensitivity of the ...
متن کاملMass-spectrometer study of the rare gases.
A stu dy of the appearance potentia ls and isotope abundance of tbe rare gases has been made \yith a Consolidated Engin eering Corp. mass spectrometer as a check on the operation of th e instrument. The res ults a re comparable to previously publi shed data. In add ition, some nell' experimental value of ionization poten tials have been obtained. Generally, good agreement of the isotope ab unda...
متن کاملCollective excitations of trapped binary mixtures of Bose-condensed gases
The linearised time dependent coupled Gross-Pitaevskii equations describing the long wavelength excitations of Bose-condensed binary mixtures are solved, in the bulk and in harmonic traps for the case where only the binary phase is present. In the former case we obtain two zero-sound branches In the latter case the dispersion law also contains two branches whose dependence on the quantum number...
