Abstract
Unconventional isotope effects (Phys. Rev. Lett., 92 (2004) 057602) as observed in high-temperature superconducting cuprates (HTSC), are explained by polaron formation which leads to a renormalization of the single-particle energies and the formation of density-density interactions. It is shown that the dominant contribution to these effects stems from the coupling to the quadrupolar Q2-type phonon mode. © EDP Sciences.
