Syllabus
Here you can find the lecture notes, schedule, extra documents, assignments, solutions, etc.
Contents
This is the first part of the graduate course in quantum mechanics, focusing on fundamental quantum theory
and their applications to simple but crucial 1D and 3D systems inclusing simple harmonic oscillators, hydrogen atoms, etc.
We will discuss quantum dynamics, central potential and theory of angular momentum.
The main topics are:
 Formal quantum theory; basic postulates and mathematics framework
 Simple 1D quantum systems; constant potential; simple harmonic oscillators
 Quantum dynamics; Hensenberg picture; spin precesion
 3D quantum systems; central potential; Coulomb potential
 Angular momentum; spin; quantum rotation; angular momenta addition
Prerequisites
 PHGN 511: Mathematical Physics
 PHGN 320: Modern Physics II (Introduction to Quantum Mechanics)
Class Policies and Suggestions
 I expect all students to attend every class. The statistics show that those seldom attend often get low scores.
 Please read the lecture notes posted online before attending class.
 During class if you have anything unclear, raise your hand and interrupt me immediately. You cannot afford
failing to understand any derivations or concepts. Do not let your confusion build up, go to my office and ask me;
otherwise you will get totally lost.
 Ipads, laptops, cellphones, and other electronics are strictly forbidden during the class. Students
using these devices frequently in classes performed poorly.
 Please go to my office often, not merely for homework problems.
 I expect you to spend about 10 to 15 hours weekly to study the contents (35 hours) and finish homework (610 hours).
If you use a lot more than 15 hours per week, please let me know and I will try to help you out.
 If you have any suggestions, concerns, worries, frustrations, etc, please let me know as soon as possible.
You may send me email, talk to me personally, or contact the class coordinator, Matt Jones (matjones@mymail.mines.edu), who is responsible for contacting me immediately if they have any feedback from the class.


Homework Assignments
 Homework will be assigned on Wednesday, due on next Thursday at 5 PM to TA's mailbox.
 Late due homework will get ZERO point, so just submit even incomplete.
 You can turn in homework late (at 9 AM the following Monday to my office) twice without any reasons.
 You need extraordinary reasons to get my permission to turn in late more than twice or later than Monday 9 AM.
 You need to let me know 24 hours before the due time for any delay and get permission if beyond the limit.
 Totally there are about 12 assignments with varying total points each (some might have bonus points).
 Clear and detailed derivations are crucial to get good scores.
 Please try NOT to use Mathematica if possible. Mathematica is a great tool for visulization, solving complicated
while trivial problems like matrix diagonalization, etc, but relying on it will hurt your analytical skills.
 But you can use Mathematica if not explicitly written in a problem, and you shall use it if I ask you to do so.
 I will try to inspect the graded homework as much as possible.
 Go to my office to get homework grading errors corrected within one week after you get your
assignments back.
Academic Integrity
Homework assignments have to be done INDEPENDENTLY. Group discussions are encouraged
but you still need to finish the problems all by yourself (never ever copy other's work), and report it
(with whom you discussed) in a short note at the end of your submitted homework. If you use any materials
from papers, online resources, and books other than the textbook, please also report in your note.
No deduction will be made if you report; otherwise I treat it as an academic integrity violation. I don't encourage
you to search internet for answers, instead, read the lecture notes and textbook, discuss with your classmates, and
talk and/or email to me.
The Colorado School of Mines affirms the principle that all individuals associated with the Mines
academic community have a responsibility for establishing, maintaining an fostering an
understanding and appreciation for academic integrity. In broad terms, this implies protecting the
environment of mutual trust within which scholarly exchange occurs, supporting the ability of the
faculty to fairly and effectively evaluate every student's academic achievements, and giving
credence to the university's educational mission, its scholarly objectives and the substance of the
degrees it awards. The protection of academic integrity requires there to be clear and consistent
standards, as well as confrontation and sanctions when individuals violate those standards. The
Colorado School of Mines desires an environment free of any and all forms of academic misconduct and
expects students to act with integrity at all times.
Academic misconduct is the intentional act of fraud, in which an individual seeks to claim credit for the work and efforts of another without authorization, or uses unauthorized materials or fabricated information in any academic exercise. Student Academic Misconduct arises when a student violates the principle of academic integrity. Such behavior erodes mutual trust, distorts the fair evaluation of academic achievements, violates the ethical code of behavior upon which education and scholarship rest, and undermines the credibility of the university. Because of the serious institutional and individual ramifications, student misconduct arising from violations of academic integrity is not tolerated at Mines. If a student is found to have engaged in such misconduct sanctions such as change of a grade, loss of institutional privileges, or academic suspension or dismissal may be imposed.
Exams
 Three exams will be scheduled: two onehour inclass midterms and one twohour final.
 In each exam there are conceptual questions (about 45%) and problems (80%), but I won't scale your scores, i.e., there are 25% bonus.
 Conceptual questions are maily from the questions we discuss in class.
 Problems in exams are similar (even identical) to those in homework assignments.
 Exams are closedbook, with essential equations and formulae provided (should be more than you actually need).
 If you have hard time memorizing an equation or formula, it means they will be given in tests if needed.
 Go to my office to get test grading errors corrected. But you also need to do so within one week after you get your
graded tests back.
Grading
Homework (50%) + Midterm Exam (2 × %14) + Final Exam (22%)
A: ≥ 95%, A: 9094%; B+: 8589%, B: 8084%, B: 7579%
C+: 7074%, C: 6569%, C: 6064%; D: 5059%; F: 049%
In practice, the class is graded on a modified curve, so that the average is about 85% or better.
Any modifications will be only upwards, and be applied to everyone equally.
Specifically, the average of every exam (125 points each) will be adjusted
at least equal to 80 by adding a common number to everyone. The homework average is expected to be much higer than 80
(last year, PHGN 520 was 90 and PHGN 521 was 92), so normally no adjustment is required.
If necessary, more points will be added until more than 2/3 are B or better (B, B+, A and A).


Required Textbook
Modern Quantum Mechanics, by J. J. Sakurai and J. J. Napolitano, Addison Wesley, 2nd Edition, 2010.

Recommended Books

Lectures on Quantum Mechanics, by S. Weinberg, Cambridge University Press (November 30, 2012).
This new textbook was written by Steven Weinberg, Nobel laureate in physics and probably the most important
living physicist. I like this book very much.

Quantum Mechanics with Basic Field Theory, by B. R. Desai, Cambridge University Press, 2009.
This is a modern QM textbook, covering the basic field theory which normally is not presented by other textbooks.
But this version has a lot of typos, and it is pretty dry  no enough explanations and physical motivations.

Quantum Mechanics in a Nutshell, by G. D. Mahan, Princeton University Press, 2008.
This is also a modern QM textbook, covering many latest developments and interesting applications of QM, particularly
in condensed matter physics. But it is not an easy book for graduate students.

Quantum Mechanics: Fundamentals, by K. Gottfried and T.M. Yan, Springer, 2nd Ed, 2004.
Probably the best QM textbook for graduate students.

Quantum Mechanics, by E. Merzbacher, Wiley, 3rd Ed, 1997.
A classical QM textbook, very well written and easy to read. But it is slightly outdated.

Principles of Quantum Mechanics, by R. Shankar, Springer, 2nd Ed, 1994.
An excellent textbook for QM I, but it lacks the depth for QM II.

Quantum Mechanics NonRelativistic Theory, by Landau and Lifshiz, ButterworthHeinemann, 3rd Ed, 1981.
A great book for theoretician, but it is outdated now.

Quantum Mechanics, by A. Messiah, NorthHolland, 1959; Dover, 1999.
One of the best QM textbooks so far, covering a wide range of traditional topics thoroughly.
