Can i ask you a question?
Is it legitimate try to find superconductivity without electron pairing and without RVB?
We know in plasma physics 'negative energy waves". Those waves are famous for diminishing total energy of plasma (nonpairing!!!!) electron waves plus ion's energy if ions become moving with some velocity V.
Why "superconductivity" physicists want nothing of solid state electron plasma???
It sure took you a long time to follow up, considering that this thread has its last activity in 2009!
It is legitimate to find other mechanism. It is NOT legitimate to make your speculation on here without first publishing it in a peer-reviewed journal. Making hand-waving claim that you just did requires no expertise. Just because something has "diminishing total energy" doesn't mean there is long-range coherence! And it would be nice for you to, for once, apply whatever it is you are pushing and show how, for example, it jives with the results we get out of ARPES, neutron scattering, etc.
On second thought, don't do that. Just collect your thoughts and publish them FIRST. I'm not interested till then.
