Physics of Disordered Systems

This course consists of five main topics,

1- An introduction to stochastic processes,

2- Diffusion-Reaction processes in one dimension,

3- Basic Properties of Polymers

4- Neural Networks

5- Spin Glasses.

There are no definite textbooks or lecture notes for this course, for each subject I will introduce appropriate references. The prerequisite for this course is an understanding of elementary statistical mechanics.

The time schedule of the course is here.

The lecture notes are available as follows: Note that these are preliminary notes and are by no means complete or polished. They are just a reminder of some topics.

Lecture 1: Elements of probability, Part I

Lecture 2: Elements of probability, Part II.

Lecture 3: Elements of Stochastic processes, Part I.
