This is a continuation of quantum optics from last term. This course will provide a broad overview of quantum-mechanical interactions between light and matter. We will focus mainly on light-atom interactions and thus we will also do some atomic structure.

**Recommended Texts:**

- Loudon,
*The Quantum Theory of Light*(QC446.2 .L68 2000) - Meystre and Sargent,
*Elements of Quantum Optics*(QC446.2 .M48 1999)

Note that the above books are not required, and we will not follow any particular text. The above texts are useful references, however. There are many other excellent standard texts that you may find useful for this course, some of the classics and good modern works are listed here. Titles with call numbers are on reserve in the science library. You should consider obtaining the Dover titles, since they are cheap.

Grades for the course will be based on homework and a take-home final exam. The relative weights will be as follows:

- Homework: 50%
- Final exam: 50%

**Homework:** about 4-6 problem sets will be assigned during the term.

**Final exam:**
the final exam is a take-home exam, and is due by noon on Tuesday, 20 March.
It will be assigned one week in advance.

**Pass/fail grading option:** a passing grade requires the equivalent
of a C- grade on all the course work (homework and final).

This is a **tentative** outline of topics we will cover in this
(and the following) course in the sequence.
Note that this is *way* ambitious for the probable duration of this course.
