Aim: PHY 4523 is designed to be a second course in the physics of many-particle systems. You should already have taken a course in classical thermodynamics -- the description of bulk equilibrium states using a few macroscopic parameters, independent of the microscopic details of those systems. PHY 4523 explores alternative approaches involving the statistical treatment of the (quantum mechanical or classical) dynamics of individual particles. Statistical mechanics is a very general framework for analyzing equilibrium systems which also provides a microscopic basis for thermodynamics. We will look at many applications of statistical thermodynamics taken from different areas of physics. The course will also touch on nonequilibrium situations, which must be treated using the more cumbersome machinery of kinetic theory.

Pre-requisites: It will be assumed that you have successfully completed an introductory course in classical thermodynamics at the level of PHY 3513 (Thermal Physics) or PHY 3062 (Accelerated General Physics III). Specifically, you will be expected to have a sound working knowledge of Chapters 1-3, 5, and 6 of Callen's book. (Most, but not all, of this material can be found in Chapters 2-5 of Reif.) Some experience with quantum mechanics will be advantageous but not absolutely necessary.

Homework: Problem-solving is integral to mastering any area of physics. Most weeks you will be assigned problems to be turned in the following week. You will also be recommended to attempt additional problems. You should make a good-faith attempt to tackle the problems on your own. However, do not spend an inordinate amount of time on any one problem. If you get stuck, feel free to discuss your conceptual or technical difficulties with other students or with the instructor. Constructive collaboration is encouraged.

The homework will account for half your overall score on PHY 4523. This weighting is designed in part to encourage you to keep up with the course. For this reason, assignments turned in late will be subject to a significant penalty. You will lose 25% of your score for work turned in up to the first class meeting after the due date, after which time a 50% deduction will apply. (Each student will receive a waiver of the preceding penalties for one assignment during the semester.) No credit will be awarded for homework submitted after the solution has been distributed to the class.

Exams: There will be two 2-hour exams -- a mid-term and a final. The exams will not merely require memorization and regurgitation of material covered in lectures and homework. (Formula sheets or textbooks will be allowed; details will be announced nearer the time.) The emphasis will be on application of concepts and methods to fairly straightforward problems, some of which may deal with unfamiliar situations.

Grade: Your grade will be assigned on the basis of an overall score, derived as follows:

homework
mid-term
final
50%
25%
25%
There will also be an extra-credit assignment which will allow you the chance to compensate at least partially for missed homework or a poor performance on one of the exams. The letter grades will be assigned on a curve.
