This book is work in progress. This book is not completed and not proofread. You can use this book
currently as a basis for following through the material presented in the course. However, you should
never blindly copy formulas an apply them. The chances that there are still errors is too large.
This book provides an introduction into the quantum mechanics of the interacting electron gas.
It aims at students at the graduate level, that already have a good understanding on one-particle
quantum mechanics. My aim is to include all proofs in a comprehensive and hopefully water-tight
manner. I am also avoiding special systems of units. I consider this important in view of a large variety
of notations, differing definitions etc. While the proofs have the advantage to train the student to
perform the typical operations, it clutters the course with material far from applications. Therefore,
I have placed many of the more detailed derivations into appendices. On the graduate level, the
student should be able to follow the proofs without problem. It is strongly recommended to follow
through the derivations. |
