Textbook: Modern Physics by R.A. Serway, C.J. Moses and C.A. Moyer

Previous offerings: Here is the weblink download for the same course I taught in Spring 2013. And here is the weblink for the offering in 2009 download  and  weblink for the offering in 2011 download with all the video recordings, assignments, exams and their solutions.

This is an evolving course. The grading scheme is as follows

Quizzes (4)20%
Homeworks (5-6)20%
Midterm (one)25%
Final exam (one)35%

I have the liberty to vary the scheme by +5% or -5%.

Feynman Lectures on Physics Vol. 3: Chapter-1, 2, 3

Quantum computing:

Quantum mechanics:


  • Modern Physics by Serway, Chapter-12, (page 447-457)
  • Non-Classical Physics Beyond Newton’s View by R. Harris, Section 8.9 (page 382-388)
  • New mechanisms for laser cooling: William Phillips Nobel banquet speech. Skim through it at least and look at the basic diagrams.
