Greetings from /wg/
Can someone explain the Dirac notation for a key vector with 2 entries? like | J M >. Every single book/video I have seen only explains that a key vector with 1 entry like | A > is a column vector with entries (A1...A2...etc)
What if it has...2 entries? Vectors with two entries like |s m> and |1/2 1/2>, or three entries like |1/2 1/2 1/2> seem to be far more widely used than single entry vectors anyway...Why does no one talk about this?
