Operator C = I+><-I + I-><+I
Wavefunction PSI = Q I+> +V I->
C PSI = Q I-> + V I+>
note the I is just a straight line (BRAKET vectors), the next step is where I get confused, p is subbed in and the ket vectors switch places...
C PSI = pQ I+> + pV I-> <---- why??
therefore
V = pQ and Q = pV
which gives p^2 Q = Q therefore p = +/- 1
why can p be subbed in and the ket vectors switch around, i.e. I-> no longer with Q and I+> no longer with V
thanks
