Would the analogy of a Newton's cradle help here? Maybe the current 'impulse' pings through the stationary orbitals and flicks the tail-end charlie off the far side to continue the current?
(The last orbital refills thermally.)

SCs will Josephson couple only to other SCs over distances ~10nm, scanning tunnelling microscopes work at a range of .5nm. Schroedinger does apply for the STM which works happily on an active super-conductor with NO Josephson current. So the entity that Josephson couples cannot be an electron, or a ...

In fact the charge carriers in most, if not all, the traditional superconductors discovered to date, are all singly-charged.
Who or what tells us this?

Also you seem to be saying that single electrons can form a BEC, despite being fermionic?

Thanks very much B.
I hope your kindness doesn't prove too burdensome.

It seems clear that there are two separate elements to this fiasco. One is the reporting of a truly extraordinary phenomena, the other is the interpretation of the phenomena. It is a symptom of the malaise in Academia that they should seek to suppress your results. Even if they considered them suspe...

I apologize, a nanotube would have left obvious pitting of the surface. Ok, the Josephson AC effect is a candidate. The frequency should be 2*e*V/h, which will give an equivalent wavelength of c*h/(2*e*V) . For the 800V you quote this gives 7.7nm which is obviously a lot shorter than what you saw. I...

Er Wow!! So you smacked the surface of diamond very hard with O ions to get interstitial atoms. Then had a small (How small?) gold ball brought near (in nms?) the surface, presumably with a voltage (how much?). You were then able to pull back the ball maintaining electrical contact to a max of 150 m...

There is no light caused by the AC effect. That is just saying that with the frequency Standard set by caesium and the perfect voltage to frequency conversion of the AC effect one can define a volt Standard. Intriguingly you see the bose mass as a single unit, with which I fully agree. A conduction ...

Thanks man. Actually when we get on to my model of SC the question as to whether N bosons is actually N separate entities becomes very relevant.

In precision metrology, the Josephson effect provides an exactly reproducible conversion between frequency and voltage. Since the frequency is already defined precisely and practically by the caesium standard, the Josephson effect is used, for most practical purposes, to give the definition of a vo...

Thank you, but what I'm really interested in is how Schroe. compliant tunnelling can cause a DC voltage to give rise to an AC current so accurately that it was used as the international standard definition of a volt. There are many theories that explain bits and pieces of SC but all are contradicted...

You are wrong. Superconduction is completely modeled by the Schroedinger equation That is the hypothesis we are discussing, we are trying to decide whether it is right or wrong. The Josephson AC and DC effects are established lab results, I'd be intrigued to see how you feel electrons from below th...

Are a group of bosons waves or particles?

Bosons are defined as entities displaying Bose-Einstein statistics. The core of B-E statistics is that N bosons in the ground state have precisely one way (ignoring degeneracy) of entering the first excited level. This makes no sense until one considers shots of vodka in a bottle. It does make sense...

This is a super-conduction thread! I've started another if you wish to discuss wave/particle duality. So JFP thinks that all super-conduction effects can be explained by electrons in orbitals that are higher than the fermi level due to a local interstitial atom as I understand it. Wiki on Josephson ...

Ok, so one of the best SCs is Niobium Tc about 12K, so I guess that requires a cryostat, ie. a vacuum, so any papers on Josephson coupling with Nb should give us data?? But generally we want to find the largest known J coupling in vacuo?? Neither of us have academic access so help would be appreciat...
