Query: Localization of low-frequency oscillations in single-walled carbon
  nanotubes   New phenomenon of a weak energy localization of optical low-frequency
oscillations in carbon nanotubes (CNT) is analytically predicted in the
framework of continuum shell theory. This phenomenon takes place for CNTs of
finite length with medium aspect ratio. The origin of localization is clarified
by means of the concept of Limiting Phase Trajectory, and the analytical
results are confirmed by the MD simulation of simply supported CNT.
