difficult and very important ideas such as the reciprocal lattice, and therefore it contains a large number of “basic concepts” questions. Chapter 3, on the other hand, is conceptually less difficult and contains only a few of them. Many more of this type of questions along with their solutions can be found on my website at www.philiphofmann.net.
The multiple‐choice questions have only one correct answer, or, if several correct answers exist, there is an explicit option to choose this, e. g., “C. Both A. and B. are correct.” In some cases, there is an overlap between a “basic concepts” question testing a conceptual understanding of a subject and a “problem” with a more in‐depth treatment of the same question.
My thanks go to the 2021 class of the Statistical Physics and Solid State Physics course at Aarhus University for testing much of the new content, as well as to the teaching instructors Paulina Majchrzak, Alfred Jones, Michael Iversen and Nikolaj Rønne. I also thank Davide Curcio for introducing me to a new set of advanced writing tools and Charlotte E. Sanders for many helpful comments on the manuscript.
