Comment on 'Attempts to test an alternative electrodynamic theory of superconductors by low-temperature scanning tunneling and atomic force microscopy'
arXiv:1612.00293
Abstract
It is argued that alternative electrodynamics of superconductivity proposed by Hirsch lacks mathematical rigour and it is conceptually flawed. Gauge non-invariance of the theory makes justification of the experiment reported in [arXiv:1607.05060] to test its prediction doubtful. It seems even with improved techniques the outcome would remain inconclusive.
