Abstract
Coexisting electronic correlations and electron-phonon interactions have been proposed to lead to dynamic polaron-tunneling behavior for the axial oxygen in . Emphasizing nonlinear and nonadiabatic effects, we show that this description leads to distinctive predictions consistent with structural, optical, and inelastic neutron-scattering data in the axial direction.
