Quantum Mechanics

**Instructor:** Hsin-Chia Cheng (cheng [at]

**Time & Place:** Tue & Thu 10:30-11:50AM, 148 PHYSICS

**Office Hours:** Thu 12-1 PM, 158 Roessler

**Website:** http://www.physics.ucdavis.edu/~cheng/teaching/215A-f22

TA: Matthew Staab
(mcstaab [at] ucdavis.edu, Office: 209 Physics), Office Hour: Fri
1-2 PM, 80 Physics

** Textbook: **The recommended books are "Modern
Quantum Mechanics," by J. J. Sakurai and J. Napolitano, 3rd
Edition, and "Principles of Quantum Mechanics," by R.
Shankar, 2nd Edition. They are widely used as textbooks for
graduate level quantum mechanics course nowadays. Another good new book is
"Quantum Mechanics: An Experimentalist's Approach" by Eugene
Commins. We will not follow exactly the order of these
books but the emphasis will be similar. Owning one of these books
is not required. Nevertheless it is recommended to have a
graduate-level quantum mechanics textbook for your own reference.
Lecture notes will be posted on Canvas

**Homework: **Homework assignments will be posted in the on
the Canvas course page. There will be homework assignments mostly
every week.
The homework should be
submitted to** Gradescope**. We will use **Gradescope** to handle the grading
of homework and exams.
No late homework will
be accepted so even if you
couldn't finish you should turn in what you have done. The
solutions will be available on the Canvas course website soon
after the deadline. Doing the problem sets is an
extremely important part of learning. You can't learn the subject
by just listening to the lectures without working through things
by yourself. They also contain some of the important topics that
we won't be able to cover in class. Many homework problems will be
challenging. They are not the type of plugging numbers into
equations but require a lot of thinking. In this way you can have
better understandings of the subject. You are encouraged to
discuss the problem sets with your classmates, TA and me, but you
are not allowed to copy other people's homework or solutions provided by online
helpers such as Chegg. Each of you is required to write
up your own homework following your own understandings. Each
problem set is due about one week after its assignment.

**Grading:** Homework 40%, Midterm (Tentatively scheduled on
Tue, Nov. 1 in class) 24%, Final (Thu, Dec. 8, 6-8 PM) 36%

**Outlines of the course:
**

- Introduction and Mathematical Preliminaries
- The Rules of Quantum Mechanics
- Time Development Operator, Hamiltonian, Foundations of Wave Mechanics
- One Dimensional Problems
- Simple Harmonic
Oscillators

- Path Integral Method

- Symmetries
and Theory of Angular Momentum (if time permits, will probably
only start the topic)
