Timeline for Why is it easier to calculate $\langle \chi|j\rangle\langle j|A| i\rangle\langle i| \phi\rangle$ than $\langle \chi|A|\phi\rangle$?

@user36790: I don't know what \SPG stand for but you can always define a new command with \newcommand{name goes here}[number of parameters]{and description} Feel free to check the wiki page for more information.

This way you have to compute the "matrix elements" of A in a basis that you chose. If you clever you do this using states i,j where you know what happens if you apply A | |

I think I should notify you that you haven't defined \SGP etc in $\LaTeX$ hence MathJax doesn't render.
