Important Note. These are my personal lecture notes, that I prepared for my personal use as part of the preparations for teaching this module. I post them here for the sole purpose of assisting the students learning this subject.
I make no claim of originality. I am basing a large part of the text on the books by Claude Cohen Tannoudji, Bernard Diu and Franck Laloe, on the book by B.H. Bransden and C.J. Joachain, and, to somewhat lesser extent, on several other textbooks. In preparing these notes, I was also using the lecture notes given to me by David Rea and Eoin O’Reilly.
Special thanks to Elad Pe’er, David Rea and Andreas Ruschhaupt for proof reading the notes and many useful comments.
(Note: my lecture notes are constantly being updated.)
