Commutators on a discrete QM lattice = ?
Please let me know if any of the following is unclear:
I was thinking about how you could go about doing QM not in a continuous space but instead on a lattice, take 1D for simplicity. Let's use a finite (not countably infinite) number of positions say...
You say that the formula is valid only for large values of of z.
Total field at P:
- \frac{q \eta}{2 \epsilon_{o} c} i \omega x_{o} e^{i \omega (t- \frac{z}{c} )}
Thanks for the link to the equation tex thingy.
Just so you know my source for this equation:
On page 283 of Feynman lectures on...
Assume we have a plane of oscillating charges described by x=xoei(omega)t.
The total field is given by E=- \frac{\etaq}{2\epsilonc}i\omegaxoei\omega(t-z/c) . (Can someone point me to a website where I can learn to type in these formulas and not not have them suck?)
Ignore that weird looking x^o...
