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))

TL;DR

This paper critiques a recent reinterpretation of oxygen isotope effects in cuprate superconductors, arguing it is mathematically and physically flawed, violating fundamental principles like the Anderson theorem and Coulomb law.

Contribution

It provides a critical analysis demonstrating the inaccuracies and violations in the recent reinterpretation of isotope effects in high-Tc superconductors.

Findings

The reinterpretation violates the Anderson theorem.

It contradicts Coulomb law principles.

The critique clarifies the correct physical understanding.

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.
