Text

Required text:
Principles of Quantum Mechanics, by R. Shankar, Springer (2nd edition, 1994).

Supplementary readings:
Lectures on Quantum mechanics, by G. Baym, Benjamin/Cumings (1973)
--graduate level book
Quantum Mechanics, by F. Schwabl, Springer (2001)
--clearly written introduction; good basis for the author's book on advanced quantum mechanics.
Introduction to Quantum Mechanics, by Griffiths, Prentice Hall (2nd edition, 2004)
--undergraduate book, excellent for filling some lack in qm
Quantum Physics, by S. Gasiorowicz, John Wiley (1974)
--introductory book on quantum mechanics
The infinite well and Dirac delta function potentials as pedagogical, mathematical and physical models in QM, M. Belloni and RW. Robinett, Physics Reports, 2014

There are many books on quantum mechanics in the library that almost all cover the material presented in the lectures. Please explore them to see different approaches to our topics.

Course Content

Tentative course calendar

This course provides an introduction into quantum mechanics at the graduate level. We will cover the postulates of quantum mechanics, the Schroedinger equation, one-dimensional problems, the harmonic oscillator and supersymmetric quantum theory, Heisenberg's uncertainty relations, symmetries and consequences, Qm in 3-dimensions, angular momentum, spin, addition of angular momenta, the Hydrogen atom

Homework

homework assignments

Homework will be assigned weekly and will be due by 4:00 pm on the following Wednesday, unless explicitely altered at the time of assignment. Late homework will not be accepted. Finished homework should be placed in the designated box in the main office of the Physics Department. Homework assignments and solutions will be posted in the glass case in the Physics Department hallway. I HIGHLY appreciate it if you RECYCLE paper for your homeworks!
Paper, Presentation Explore the fun and "strange world" of quantum mechanics! Explore a topic related to this course on your own. This can be an application of quantum mechanics in medicine, in nanotechnology, biology, etc. It can be on non-hermitian quantum mechanics, quantum chaos, alternative theories like Bohm's pilot wave theory, Feynman's path integrals, a bridge between classical and quantum mechanics; it can be on Bell's theorem, the EPR experiment, quantum computation, quantum kryptography; many other topics are possible, follow your own interest. This topic will be explored by you in a concept paper and an oral presentation. A good way to get started is to browse through "physics today" to find an interesting article on quantum mechanics that you will prepare such that the class can understand. The project needs to be based on a published paper or advanced text book, online sources like Wikipedia are not allowed.
Concept Paper: The concept paper starts with the hypothesis to be addressed in the paper; and continues with the explanation of a quantum mechanical concept. the focus is on how the concept is explained and whether it can be understood by an undergraduate physics student that had an introductory QM course. The use of any formula needs to be approved by the instructor at latest 2 weeks before the paper is due. The concept paper represents the basis and key message of the presentation. Goal is to formulate the concept as a take home message that is soo well explained that the audience will never forget about it; no "hiding" behind a sequence of formulas or derivation. The paper should consist of 2 pages (11pt, standard margins and single spacing) of text; 3-5 references, figures, and formulas (if approved) do not contribute to the 2 pages. The topic should be discussed with the instructor, and is due Oct 12; the paper is due Nov 16. The project needs to be turned in as a HARD COPY and as PDF file. The grade is determined from physics (70%) and style (30%) of the paper. The physics part includes hypothesis formulation, correct physics, level covered, how explained, how introduced, understanding, terms defined. The style part includes organization and structure, references given, figures referenced, writing style.
Presentation: The quantum concept will be presented to the class in a 10 minutes presentation the week before finals. The presentation needs to be turned in as a pdf-file, at latest the day after presentation. The grade is determined from clarity of presentation (50%) and content (50%). The clarity of presentation includes board/transparency use, clearity of writing/slides, references used, blocking board/screen, speaking clearly and loud, speed of speach, facing class and eye contact, dealing with questions. The content includes appropriate level, enough details, terms introduced before used, correct physics, how explained.
Examinations A one-hour in-term examinations and a two hour final examination will be held during the semester. In-term exams will be held in the classroom. The exams will be closed books and closed notes.
Midterm exam (inclass) Friday, Oct 28
Shankar, approx chapt 1-8
Final exam Monday, Dec 12, 3:15-5:15pm Shankar, approx chapt 1-12
Grading The maximum score for each homework will be 100 points. A solution (homework, exam) that presents nothing more than a restatement of the problem will receive zero credit. Illegible work will not be graded. Grades A - D (including +/-) are assigned equal weight for total credits between 40% and 100% unless otherwise noted. So A+ (>95), A (>90), A- (>85), B+ (>80), B (>75), B- (>70), C+ (>65), C (>60), C- (>55), etc. A total score below 40% results in an F. For the final grade homework, exams, etc. will be weighted as follows:
Homework 25%
Presentation 10%
Concept Paper 10%
Midterm 25%
Final exam 30%
Course policies Attendance at lectures is expected. Active class participation, questions, comments on newspaper articles on modern physics are extremely welcome in the lectures. A missed exam will receive 0 credit unless the instructor is notified by email, phone, etc before the exam starts. Make-up exams will be individually scheduled with the student.
Student Obligations As students of UAF, you are bound by the policies and regulations of the University of Alaska, UAF rules and procedures, and the Student Honor Code. You are obligated to make yourselves familiar with all conditions presented in the UAF Catalog. Plagiarism on homework, or on exam, or on presentation or on paper will result in a failing grade.
Disabilities Services The Office of Disability Services implements the Americans with Disabilities Act (ADA), and insures that UAF students have equal access to the campus and course materials. If you have any kind of dissability, please ensure that you go to the dissabilities services program coordinator. I will work with the office of disabilities services (203 WHIT, 474-7043) to provide reasonable accomodations to students with disabilities.
