Query: Phonon anomalies and dynamic stripes   Stripe order where electrons self-organize into alternating periodic
charge-rich and magnetically-ordered charge-poor parallel lines was proposed as
a way of optimizing the kinetic energy of holes in a doped Mott insulator.
Static stripes detected as extra peaks in diffraction patterns, appear in a
number of oxide perovskites as well as some other systems. The more
controversial dynamic stripes, which are not detectable by diffraction, may be
universally present in copper oxide superconductors. Thus it is important to
learn how to detect dynamic stripes as well as to understand their influence on
electronic properties. This review article focuses on lattice vibrations
(phonons) that might show signatures of the charge component of dynamic
stripes. The first part of the article describes recent progress in learning
about how the phonon signatures of different types of electronic charge
fluctuations including stripes can be distinguished from purely structural
instabilities and from each other. Then I will focus on the evidence for
dynamic stripes in the phonon spectra of copper oxide superconductors.
