I don't have an opinion on this, as I am still (and always will be) learning QM. In short, IMHO, there is no

I would say read Griffiths and other books you can find in your library. But just don't read them as story books...solve problems and get stuck, so you can learn something. Work on the project alongside, there's no harm in doing that. You might want to check out this book: https://www.amazon.com/dp/058235692X/?tag=pfamazon01-20. Its a standard text and most likely your library has a copy. Good for both Perturbation Theory and Hartree Fock, esp if you're starting out.

I agree. I doubt they expect you to be an expert in what the are doing. If they are, then they should not be looking for first year REU Participants. You'll be fine. Keep doing what your doing and learn quantum mechanics at a pace where you can absorb it and do problems. Don't rush through the learning process. Good luck to you!

I'm sure you'll do great. The fact that you have landed with a project of this nature right after your freshman year is indicative of the confidence your REU judges/supervisors have in you. [Sidenote: Personally, I believe its possible to learn QM given your background (I myself started taking an interest long before my freshman year and that helped me learn a lot of neat techniques which helped in various other courses) but perhaps others may disagree.] So, just enjoy yourself, read whatever interests you...there are so many QM books out there. Ask lots of questions and solve problems. You will be fine.

Good luck!

Check out the Schaum's outline in QM......

What I studied in my two semesters of Undergrad in QM using GRIFFITHS, SECOND ED.:

(note: Linear Algebra is helpful to understand some of the basic concepts of QM.)

Schroedinger TIme-Dependent Equation:

get a good feel for how to handle the basic potential wells (infinite, finite, ones when d(Psi)/d(x) is not continuous),

know the difference between scattered states and bound states in the wells, (and how they relate to discrete and continuous spectra of eigenvalues, CH 3.3 Griffiths).

The harmonic oscillator (eek!), (extra credit: think of when and how to apply ladder operators)

*Formalism (ch. 3)*

Bohr's three postulates (Observables: (3.1, 3.2))

Statistical Interpretation (3.4)

Uncertain Principle (3.5)

*CH. 4, QM in 3D*

Read and understand ALL of the general ideas in this Chapter. It leads up to the the atom, and an interesting consequence of having a third dimension.... (I'll leave the surprise for you, you'll recognize the quantities that come out of 3D I'm sure, they're quite popular).

When you read this chapter, don't get caught up on trying to memorize all the tables it has. If you took Electrodynamics with Griffiths, you should have a basic understanding of spherical harmonics and all that Legendre jazz.

*CH 5, Identical Particles*

We only did 5.1 and 5.2 here. The concept of Identical Particles is VERY important and interesting. We glanced at 5.4, but not much work was done in it. Have a look at the Three different distributions though (Maxwell-Boltzmann, Fermi-Dirac, and Bose-Einstein) and try to interpret the equations physically using your knowledge of Identical Particles vs. distinguishable.

*Ch 6, TIme Indie. Perturbation Theory*

Get 6.1 and 6.2 down pretty good, have a look at the rest of the chapter for how the basic concept applies to the atom.

*Ch 7, Variational Principle*

7.1 and 7.2, (another important concept, not as interesting to me, but powerful tool nonetheless.)
