Updated notes

I've updated the notes with a slightly expanded and improved treatment of the finite-temperature path integral, section 4.6. This version has v2 in the name.

Schedule of remaining lectures

The remaining lectures for this course will take place on Tuesday, Wednesday and Thursday April 2,3,4 at 4 PM. As before, the Tuesday and Thursday lectures will be in room 304 of LHC while on Wednesday it will be in room 301.

Thereafter, in the following week we will have two tutorial/revision lectures, one on Monday April 8 at 6:05 PM. The second will be on Wednesday April 10 at 4 PM. Both these tutorials will be held in the Main Building in Physics Seminar Room 31 on the 2nd floor. There will be no lectures on April 9 and 11 as these are IISER holidays.

The schedule for the course has been updated to reflect the above changes.

There will be no more course lectures after April 10. I will be available in my office up to and including Monday April 15, after that I will be away from Pune. 

The final exam is scheduled for Friday April 26 from 10:00 AM to 12 Noon.

Practice problems uploaded

I have uploaded a set of problems for practice. They are in the shared folder as Problem Set II.
