Physics 846 - Statistical Physics I - Fall 2003
Current reading assignment
Please read sections 4.A, 4.B, 4.C, and the introduction to section 4.D of the textbook. When you are done, fill out the questionnaire. The deadline for this assignment is Thursday 11/13 at 3:59am, i.e., you would be well served to finish it by Monday evening. You will not be graded on which answers you give but you are required to fill out the form.

The grades were distributed as follows:
This class and the Statistical Physics II (847) class in the winter quarter will give an overview over thermodynamics and statistical physics. At the end of the winter quarter we will have explored the phenomenology of systems with a large number of particles and what methods exist to deal with this large number of degrees of freedom. We will be able to make very general statements on any such system as well as to analyze specific models.
The fall quarter will cover the following topics:
- thermodynamic variables
- laws of thermodynamics
- thermodynamic potentials
- thermodynamic stability
- Maxwell relations
- classification of phase transitions
- Clausius-Clapeyron equation
- microscopic definition of entropy
- microcanonical ensemble

Don't be afraid about the size of the book. We will cover only selected chapters in class. Specifically, we will concentrate on the main sections of chapters 2, 3, 4, and 7. At times, we will also deviate a little bit from the textbook. However, the chapters and sections which we will not be able to cover make for a good reference on thermodynamics and statistical physics.
If you do not like the textbook or if you are just interested in reading things from a different point of view, you may want to look at the following textbooks. A long list of statistical mechanics graduate textbooks is also available at http://stp.clarku.edu/grad_texts.html.
- Herbert B. Callen, Thermodynamics and an introduction to thermostatistics, ISBN 0-471-86256-8
- Very thorough coverage of thermodynamics.
- Walter Greiner, Horst Stocker, and Ludwig Neise, Thermodynamics and statistical mechanics, ISBN 0-387-94299-8
- Good overview of both thermodynamics and statistical physics.
- Kerson Huang, Statistical mechanics, ISBN 0-471-81518-7
- Very short on thermodynamics but a good book on statistical physics.
- Leo P. Kadanoff, Statistical physics: statics, dynamics, and renormalization, ISBN 9-810-23758-8
- Very advanced book.
The grade for this class is determined by a weighted average of the weekly problem sets, the midterm exam and the final exam. There will be no curve grading and I hope that everybody will get an A. The final grades will be determined according to the following scheme:
Problem Sets (20%)
Problem sets will be handed out every Thursday in class starting on September 25 (although I will be out of town on 9/25, there will be copies of the first (shorter) problem set in the classroom on this day.) The problem sets will also be available on the course web page. The problem sets are due the following Thursday in class. Exceptions to this rule are set 5 that is due on Tuesday, November 4, and set 9 that is due on Tuesday, December 2. Students who cannot attend class are requested to give their solutions to a fellow student or deposit them in my or the grader's mailbox in the physics business office on the same day. If you have a good reason for not being able to complete your homework by the due date please contact me for approval of an extension and exclusively put it into my mailbox by the approved extended deadline. In the interest of protecting the grader from extra work due to homework trickeling in late unapproved late homework will not be accepted.
The solutions of the problem sets will in general be discussed during the second half of each Thursday's class, i.e., 11:30am-12:18pm. However, there will be a few exceptions to this rule:
- The fifth problem set will be discussed in the first half of the class on Thursday, November 6
- The ninth problem set will be discussed in the second half of the class on Tuesday, December 2
You are strongly encouraged to discuss about the problem sets (and any other aspect of the class) with your fellow students. Group solutions to problem sets by two people working together are accepted. However, the solutions have to be hand-written by both students, either alternating weekly or within one week's solutions. Typed solutions will not be accepted.
Midterm Exam (40%)
The midterm exam will take place on Thursday, October 30, 10:30am-12:18am during class. Students which have any problem with the date of the exam are asked to contact me as soon as possible. It will contain several problems which will be related to the problem sets up to the one due on October 23 (set number 4) and to the lectures up to the class on October 28. There will be one problem asking for conceptual understanding and knowledge of basic definitions. It will be a closed book exam.
Final Exam (40%)
The final exam will take place on Thursday, December 11, 9:30am-11:18am. Students which have any problem with the date of the exam are asked to contact me as soon as possible.
The exam will contain several problems which will have a close resemblance to the problem sets of the full quarter with a strong emphasis on the second half of the quarter. There will be one problem asking for conceptual understanding and knowledge of basic definitions. It will be a closed book exam.
Reading assignments (0% but required)
From time to time reading assignments of sections of the textbook will be given. These reading assignments will be announced on top of the course web page as well as in class. On days on which reading assignments are discussed in class you have to answer some questions about the reading on the web by 3:59am the day of class. Your answers will not be graded; the only requirement is that you do take the questionnaires. However, since the answers to these questions will help focus the discussion during the class to those issues you had difficulties with during your reading, it is in your owm interest to answer these questions as honestly as possible. It is also not implausible that some of these questions might reappear on the exams. In order to get a passing grade you are not allowed more than two missed reading assignment questionnaires. If you missed more than two reading assignments during the quarter, you will have to schedule an oral examination on the missed assignments with me before obtaining a passing grade.
Attendance during the lectures is not required. However, the problem sets will be closely related to the contents of the class and it is every students responsibility to keep up with announcements, etc., made in class if not present.
Students with any special needs are asked to inform me at their earliest convenience.

final exam (comprehensive) 20%
Homework is due at the beginning of class each Tuesday.
Homework late by < 48 hours, 1/2 credit. Homework late by > 48 hours, no credit.
The “midterm” exams and final exam will be in the evening at 7:30 - 10:30 p.m. in Room MPHY 213 on the designated dates: October 5, November 16, December 8.
Some topics in astrophysics will be amplified compared to the textbook's treatments, with short and simple treatments of neutron stars and white dwarfs (including the Chandrasekhar limit), stellar pulsation, the Saha ionization equation, and reactions in cosmology. Topics not in the textbook include (i) review of some techniques in thermodynamics (from Herbert B. Callen, Thermodynamics and an Introduction to Thermostatistics, 2nd Edition ), (ii) basics of the BCS theory of superconductivity (Linda E. Reichl, A Modern Course in Statistical Physics, 4th edition, pp. 224-231), and (iii) the Rayleigh-Bénard instability as an example of a nonequilibrium phase transition (Reichl, pp. 378-385).
