    Graduate Distinguishability of electrons separated by large distances

    Sorry Ben for the bad font i used. Read it again below- What is the problem in distinguishing two electrons separated by large distances, unless they are entangled. Does distinguishability mean that all electrons in the universe is somehow entangled?

    Graduate Recursion relation for C-G coefficients

    From J.J. Zakurai page no.222-225: We know that Clebsch-Gordan coefficients vanish unless m=m1+m2. Then, (1) why is that the terms in recursion relation doesn't vanish? since m1+m2=m+1 or m1+m2=m-1 in eqn.(3.7.49). (2) why is again in the example shown in eqn.(3.7.54), m1+m2=m? I...
