Jeff,
Apologies, it was Colin Walkers essay I posted the sequence outline on. I'll add it below.
The Poincare Sphere is simply what I showed in my figs lat year and experiment (photo's) this year. There's a 2nd (orthogonal) momentum pair 'hidden away' in orbital angular momentum OAM, equivalent to Maxwells 'curl' at poles, but just 'linear' at 90o on the equator left/right also opposite at 180o. Bohr didn't use it formulating QM!
100sec video here, including classical 'non-integer spins' from y & z axis rotation!!
The easy way to start is to follow through the actual mechanism using the brains visualisation skills computing power and logic. As Wheeler said, get the answer before doing the maths! The Process;
1. Start with Poincare sphere OAM with 2 orthogonal momenta pairs NOT 'singlets'.
2. Pairs have antiparalell axis (random shared y,z). (photon wavefront sim.)
3. Interact with identical (polariser electron) spheres rotatable by A,B.
4. Momentum exchange as actually proved, by Cos latitude at tan intersection.
5. Result 'SAME' or 'OPP' dir. Re-emit polarised with amplitude phase dependent.
6. Photomultiplier electrons give 2nd Cos distribution & 90o phase values.
7. The non detects are all below a threshold amplitude at either channel angle.
8. Statisticians then analyse using CORRECT assumptions about what's 'measured!
If the numbers match CHSH>2 and steering inequality >1 you've got them right.
Not this all came from the simple SR solution discussed, so allows unification both decluttered. (not that mainstream will welcome it or allow it in!) Let me know how you get on.
I'm a bit tied up with a dinner & rugby internationals this weekend so I'm scoring yours now in case I get tight for time. A well deserved boost. Well done.
