Comment on "Isotope effect in high-Tc superconductors" (D. R. Harshman, J. D. Dow, and A. T. Fiory, Physical Review B v.77, 024523 (2008))

Abstract

We show that the recent reinterpretation of oxygen isotope effects in cuprate superconductors by D. R. Harshman et al. is mathematically and physically incorrect violating the Anderson theorem and the Coulomb law.
