Solve Schrödinger Equation: Need Help

AI Thread Summary
The discussion centers on a student's struggle with solving the Schrödinger equation in a quantum mechanics course. They express confusion about the mathematical components of operators, eigenfunctions, and eigenvalues necessary for tackling the problem. Respondents emphasize the importance of reviewing textbook materials and notes to build a foundational understanding. They encourage the student to engage actively with the problem as if it were an exam question. Overall, the conversation highlights the need for self-study and familiarity with quantum mechanics concepts to successfully approach the Schrödinger equation.

Homework Statement



Hi, I've just started this new course about quantum mechanics and it begins, among others, with this question:

Well, what do you know? How familiar are you with the Schrödinger equation, and the concepts of operators, eigenfunctions, and eigenvalues?
 
Thanks for trying to help :D
I know the definitions of those terms that you have mentioned; but, I am not familiar with their mathematical components enough to use them to tackle the problem freely.
 
You've got to make an effort here if you want us to help you, schnuffi.

Suppose this were a problem on an exam. How would you start? Go back to your references (textbook, notes, etc.) and look things up, if you have to.

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...
