Reznik We report inelastic x-ray scattering measurements of the temperature dependence of phonon dispersion in the prototypical charge-density-wave (CDW) compound 2H-NbSe 2 . Surprisingly, acoustic phonons soften to zero frequency and become overdamped over an extended region around the CDW wave vector. This... [Phys. Rev. Lett. 107, 107403] Published Thu Sep 01, 2011
