Bob,
To be honest, I am unsure about this paper. The main conclusion is rather
poorly presented.
He fails to do too many things and leaves an impression that he is not fully
understanding the extent of what is being claimed.
Yet -- because of other recent results with graphene – there is
Jones—
NICE FIND.
IMHO the issue of superconductivity is fuzzy because there is a fuzzy
definition of the system of materials over which the alleged superconductivity
extends. The fuzzy question is: Is the transfer of charge between coherent
systems or within a coherent system?
