Instructor Info:  Professor Edwin Fohtung office: GD Hall 259A, email: efohtung@nmsu.edu

Textbook:  J. S. Townsend, "A Modern Approach to Quantum Mechanics," 2nd Edition (required) 
Course Overview
This is an upperdivision course for quantum mechanics, and
continues to PHY 455 "Intermediate Quantum Mechanics II". As seen in
the syllabus, the basics of quantum mechanics are taught in a
selfcontained manner. The course is suitable for undergraduate or
graduate students who like to obtain comprehensive understanding of
quantum theory and to master its mathematical treatments from scratch.
In case you do not satisfy the above prerequisites, you may still
discuss a registration with the instructor.
� It is quite important to do exercises and assignements, in order to
digest notions and methods in quantum mechanics learned in the
lectures. The assignments are not only used to help you understand the
material but� also to give you a broader insight from into the subject.
The final grade will be determined based on performance of midterm
exams and assignments (their weights are 65 % and 35 % respectively,
for now). Their problems will be largely selected from the problems
found at the end of chapters. Each midterm exam is arranged after
every chapter is completed. That is how you can study rather narrow,
clearlydefined selections of materials for every exam, while they are
still fresh in your mind. Overall it is expected that your learning is
more effective and at the same time the load by the course is less
stressful this way.
Syllabus
We plan to cover a good part of the textbook over the course of the
semesters (Fall 2014). If time permits, I will explain briefly recent
research activities related to quantum mechanics, quantum electronics
and quantum information.
1. SternGerlach experiments [Lecture note on the chapter 1]
2. Rotation of basis states and matrix mechanics [Lecture note on the chapter 2]
3. Angular momentum [Lecture note on the chapter 3]
4. Time evolution [Lecture note on the chapter 4]
6. Wave mechanics in one dimension [Lecture note on the chapter 6]
