Introduction

Polymer Physics 120/240 is a course offered once every other year as an introduction to this ubiquitous molecule. Synthetic polymers are what makes up plastics, gels, and glues. Biological polymers make up DNA, RNA, and proteins. So their role in science and technology is tremendous.

Not only that, but although polymers often appear quite goopy to the untrained eye, to us physicists they have very elegant properties owing to the self-similar behavior that they often exhibit. The self-similarity or "fractal" nature of polymeric systems makes it possible to understand systems of long polymer chains using scaling and other powerful yet intuitive theoretical approaches. These approaches have a lot of overlap with field theoretical techniques used in other branches of physics such as particle physics, yet has a more direct physical interpretation.

In this course, you'll learn about these concepts and also about computer simulations of such systems. In the past, students have done final projects, some of which have been exceptional. Last year one student's project was published in Physical Review Letters.

So for those analytically inclined, this provides an excellent opportunity to learn new mathematics and physics techniques. For those interested in computers, this course has proved very useful to improving programing skills including simulation and visualization. The languages that I encourage are C, C++, and Java.

The format of the course will depend on the number of students enrolled. In the past, typically around 10 students have enrolled, which has allowed for a lot of flexibility in the direction individual students could take.

Web resources

These are some resources I found on the web. There are many more. Let me know if there are some you particularly like.

Polymers

Path Integration

  • An introduction to path integrals by Richard MacKenzie, University of Montreal.

Monte Carlo Simulations

Useful X front end graphics library

Useful computer info

  • Tutorial for running the debugger gdb inside of emacs, by Doug Rohde, Princeton University.
  • Tutorial on writing Makefiles, by Hector Urtubia.
  • My .emacs file that invokes viper, a "vi" emulator inside of emacs. Very useful for those who only know "vi" and don't want to learn another set of arcane key-strokes.

Grades and Evaluations

    This will depend on the number and backgrounds of students enrolled. As in previous years there will be homework problems assigned and class projects involving programing or analytical work. The exact combination of these will be determined by the makeup of the class.

Prerequisites

Prerequisites are Physics 112, and 116A-B-C.
