Quantum Mechanics -- Supplemental text?

Hello,

I'm currently in a quantum mechanics class (undergraduate) that is using Griffiths Intro to Quantum Mechanics (second edition). I've taken solid state physics, electromagnetism, thermodynamics and statistical mechanics, among other physics classes, but have found that Griffiths provides too few examples for me to adequately tackle the problems in the textbook. Can anyone recommend a problem-solving oriented quantum mechanics guide or supplement that can help me out? Thanks.

I know a friend who successfully used Schuam's Outline of Quantum Mechanics... But I'd recommend that you go back and do the problems in Griffiths as the majority of those problems teach you something new about the subject as well.
 


Try "Principles of Quantum Mechanics" by Shankar. =) Its approach might be different from Griffiths since it gives you the bra-ket formalism right at the start, but I find it to be the best introductory QM book around.

Or try to review your differential equations / orthogonal functions (under linear algebra) again, Griffiths uses a lot of that. I also had the same problem as yours with his book but I finally figured out that I needed to refresh myself with those mathematical topics.

Hope this helps. Goodluck!
 


Personally I think Shankar's text is a bit more difficult than Griffiths'. If you can solve the problems in Griffiths' book then Shankar might be out of reach.
 
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
