• Important practical benefits (XI. 1)
• the optical signal is immune to electromagnetic
  interference,
• ambient conditions of pressure and temperature,
• (2) pulse-delivery is not dependent on materials
  that might
• degrade over time.

• Efficient DFT calculation of phonon dispersion
  of large diameter nanotubes
• Study of Kohn anomalies, Peierls distortion and
  LO-TO splitting in metallic tubes
• Peierls Distortion temperature exponentially
  depends on diameter, and is negligible for tubes
  normally used in experiments (ltlt1K)
