For a nice qualitative summary of Mill’s theory see the following link:
Superconductivity of planar molecules (with electrons in a 2-D system ) are
discussed in item 12 of the summary.
mass” which aside from semantics, is interesting for a number of practical
reasons in batteries and capacitors.
Side note: the first article was written by the Russians who won the Nobel
Prize in physics in 2010 for the discovery of graphene
These Dirac electrons have a linear dispersion, as if they have zero mass, and
very high mobility. Of course they must possess mass of a kind, but act like
photons and follow the same equation as massless particles that travel at C, so
you would expect some of the same qualitative behavior as photons. But they
are not moving fully at the speed of light, and they are not really massless
(despite some bad reporting). However, they can turn graphene into a
superconductor… and much more.
The understanding and use of Dirac electrons may be the hottest research topic
in physics in 2018 especially if a high temperature superconductive version of
graphene is found which exploits Dirac electron.
This is a prediction… and another is that the Dirac electron will be shown to
provide the negative charge in UDH – ultra dense hydrogen. (using a hybrid deep
electron theory which borrows from Holmlid, Lawandy, Mills, Meulenberg, etc).
