Quantum Physics - Calculating Commutators

AI Thread Summary
The discussion focuses on calculating specific commutators in quantum physics, particularly involving position operators (x, y, z) and angular momentum operators (L). Participants express frustration over vague textbook explanations and seek guidance on identifying patterns in the commutators. A follow-up question suggests repeating the calculations using momentum operators instead. There is a mention of applying operators to eigenfunctions and questioning whether the eigenfunctions of one operator are also eigenfunctions of another. The conversation highlights the need for clarity in understanding angular momentum eigenfunctions, especially for those catching up on missed coursework.

Quantum Physics -- Calculating Commutators

The problem states:
Calculate the commutators [x,Lx], [y,Lx], [z, Lx], [x, Ly], [y, Ly], [z, Ly]. Do you see a pattern that will allow you to state the commutators of x, y, z with Lz?

Unfortunately, the book that is asking this question is very vague and doesn't go into any of the math involved. Any help pointing me in the right direction would be greatly appreciated.

[Followup Question]:
Repeat the calculation with x,... replaced by px,...

Again, any help would be amazing!
Thanks!

I'll try it out

Thanks for your help!
From what you said, I assume that the commutators [x, Lx], [z, Lz], and [y, Ly] should be zero. I'll have to go to my TA to get help with the eigenfunctions of the angular momentum. I missed a week of classes, so I'm just trying to catch up =)

Thanks again.
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
