Anomalous softening of phonon dispersion in cuprate superconductors
A softening of phonon dispersion has been observed experimentally in underdoped cuprate superconductors at the charge-density-wave (CDW) ordering wave vector. Interestingly, the softening occurs below the superconducting (SC) transition temperature T_{c}, in contrast to the metallic systems, where t...
