Try to have a closer look at sugar crystals. They are anything but cubic!

I think that a wealth of this kind of experiments has been performed and published as the understanding of the breakdown of...

I had a look at your draft. In steady state, there will be an influx of Cooper pairs into the non-SC chamber and a reflux of electrons...

The pairs are in a condensate and the whole condensate has to be accelerated. The acceleration of the condensate is due to the electric...

This is a thermodynamical argument, not an argument about violation of conservation of momentum. So I think we can agree on that there...

When talking about London forces, you always need at least two atoms. Their dipole dipole interaction involves the product of the dipole...

The collision of the normal conducting electrons with the lattice preserves (angular) momentum. It is first carried by the electrons...

Of course the normal conducting electrons will slow down due to collisions with the lattice atoms. Normal resistivity. Where is the...

I really think there is a very small transient decrease of supercurrent, if you suddenly decrease the superconducting density by...

Found this interesting article: https://arxiv.org/pdf/1609.08451

In principle, this is the Einstein - de Haas effect. The electronic sub-system condenses into a broken symmetry state with...

There is no momentum conservation for the electrons alone. Momentum can always be taken up from or given to the lattice.

Breaking a pair reduces the magnetic field which leads to an electric field which speeds up the other Cooper pairs which increase the...

For me it works fine. For legal reasons I find it problematic to upload papers I do not own.
