Comparing various microscopic theories of rotating superconductors to the conclusions of thermodynamic considerations, we traced their marked difference to the question of how some thermodynamic quantities (the electrostatic and chemical potentials) are related to more microscopic ones: The electron’s work function, mean-field potential, and Fermi energy—certainly a question of general import. After the proper identification is established, the relativistic correction for the London moment is shown to vanish.
