Condensed Matter Physics

Objective of the course

This course will be helpful for students who are interested in condensed matter physics (theory or experiment) in future.
The pre-requisite for this course is mathematical methods I and II, classical mechanics, quantum mechanics I and II and statistical mechanics. This course is for 4th year BS-MS and PhD students.
