We know that Lˆx and Lˆy are Hermitian operators to do see that
to do the calculation
a) Make sure that all the steps in (2) are clear to you, and show that using some of them can also prove equality
b) Show that (2) implies the relation
(3)
between the states |l,m> and |l,m±1> with norm equal to 1, and that it is holds for the operators associated with spin.
Note: It is important to note that explicit forms of these relations are valid given the particular definitions that we are using for Lˆ±.
