Description of the course

    This is a course on critical phenomena (Fall semester of 2013)  taught be me in Sharif University of Technology. It is open to all Phd and MS students from departments of physics. At the end of the course, the student is supposed to be able to follow the the existing literature on the subject and perpare him or herslef for doing original research.


    Knowledge of statistical mechanics is absolutely necessary. Those who have not taken a course in statistical mechanics, can first go through the lecture notes of statistical mechanics. Our emphasis in the class will be on problem solving so the students are required to stuy a great deal on their own.

Sources for your study

    I will use various sources, books, review articles and lecture notes. Some of them are as follows:

  • Modern Theory of Critical Phenomena, by Shang-Keng Ma, Frontiers in Physics, Addison Wesley (1976),
  • Lectures on Phase Transitions and Critical Phenomena, by Nigel Goldenfeld, Frontiers in Physics, Addison Wesley (1992),
  • The theory of critical phenomena, An introduction to renormalization group; Binney, Dowrik, Fisher and Newman (Clarendon Press, Oxford, 1992)

Important Notes:

After each lecture I upload a pdf file in Persian which contains the main topic covered in the class and a set of problems. There will be two midterms + one final exam. Your success in these exams essentially hinges on solving these problems. Note that the lecture notes are in the form of preliminary drafts and require a lot of expansions and polishing. Hence they are not a substitute for your own study from books which you may find appropriate. Please note that these lecture notes are being developed and I may update a lecture note several times. The updates are specified by their numbers. 

Important Dates:
