Intriguing examples of inhomogeneous broadening
Francesco Ancilotto, M. Mercedes Calbi, Milton W. Cole +2
Three problems are considered in which inhomogeneous broadening can yield unusual consequences. One problem involves the energy levels of atoms moving within nanopores of nearly cy…
Lattice dilation near a single hydrogen molecule in an interstitial channel within a nanotube bundle
M. Mercedes Calbi, Ari Mizel, Milton W. Cole
We explore the ground state of a single hydrogen molecule within an interstitial channel (IC) of a bundle of carbon nanotubes. A previous (variational) study found that when many m…
Universal anisotropic condensation transition of gases in nanotube bundles
Silvina M. Gatica, M. Mercedes Calbi, Milton W. Cole
Gases adsorbed within bundles of carbon nanotubes (inside of the nanotubes or in the interstitial channels between the tubes) exhibit a variety of phase transitions with the help o…
Bose-Einstein Condensation of Molecular Hydrogen in Nanotube Bundles
Francesco Ancilotto, M. Mercedes Calbi, Silvina M. Gatica +1
We evaluate the effects of heterogeneity on the density of states of H molecules inside interstitial channels within bundles of carbon nanotubes. As temperature (T) falls, the…
Peas in a pod: quasi-one-dimensional C60 molecules in a nanotube
M. Mercedes Calbi, Silvina M. Gatica, Milton W. Cole
We evaluate the equation of state of the quasi-one-dimensional (1D) phase of C60 molecules in small carbon nanotubes, nicknamed ``peas in a pod''. The chemical potential and 1D pre…
