Query: Correlation of strontium anharmonicity with charge-lattice dynamics of
  the apical oxygens and their coupling to cuprate superconductivity   X-ray absorption spectra of both $YSr_2Cu_{2.75}Mo_{0.25}O_{7.54}$ and
$Sr_2CuO_{3.3}$ show a remarkably strong, three-way correlation between: a)
their Cu-apical-O pair distributions that constitute the Internal Quantum
Tunneling Polaron (IQTP) component of their dynamic structures; b) their Cu-Sr
pair distributions; and c) their superconductivity. Application of Kuramoto's
synchronization technique to exact diagonalization calculations of a pair of
IQTPs bridged by Sr and a planar O atom shows a first order phase transition to
a synchronized state in which a fraction of the hole originally confined to the
apical O atoms of the cluster is transferred onto the planar O. The resulting
entanglement of the conducting and dielectric layers in combination with the
$\ell = 2$ angular momentum of the synchronized IQTP dynamic network could be a
critical component of the mechanism for d-wave pairing and condensation. This
combination of experimental results and theory demonstrates the Sr-apical O
dielectric layer of cuprates plays an important role in high temperature
superconductivity via the collective charge dynamics of their IQTPs.
