Operator C = I+><-I + I-><+I(adsbygoogle = window.adsbygoogle || []).push({});

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
