Thank you so much for this clarification.. it is very helpful. Next time I will follow the right section.. new here.:smile:

ok great. I know till this step, my question is to separate these operations and get the final out put like this <u+2|aa|u> - <u+2|aa+|u> - <u+1|a+a|u>... so on and solve each one on its own, when I get any different matrix output, the term equals 0; like <u+1|u> or <u+2|u-1>... right? Cuz my...

Well, in terms of ladder operators, X= (h/2mw)1/2(a+a+) you can say = constant (a+a+) it is a real P=i(hwm/2)1/2 (a-a+) or constant (a-a+) about u and u+1 are functions; some books write them like this and others write PSI or PHI of subscript u and u+1;I couldn't type that way as there is no...

Please I need your help in such problems.. in terms of ladder operators to simplify the calculation of matrix elements... calculate those i) <u+2|P2|u> ii) <u+1| X3|u> If u is different in both sides, then the value is 0? is it right it is 0 fir both i and ii? when exactly equals 0, please...

Thank you.

ooh:sorry:. Thank you. I did it. This confusion leads me to know and register at this great form. I am happy to be here:smile:

Hello, please help me with normalization problem.. f is sin(Pi x/L) between 0, L first we use normalization formula and integrate N^2 Sin^2(pi x/L) to get N^2( L/2) Sin L/2 which equals to one ... this is my solution in the textbook his result is N^2 (L/2) My question is how he get rid of...
