Matrix Elements of Tensor Operators: The Wigner-Eckart Theorem,In this chapter, we focus on the Wigner-Eckart theorem, which allows us to calculate matrix elements of irreducible tensor components. In Sect. ., we first recall a common variant of this theorem that is usually covered in quantum mechanics courses. In this context, we also introduce the concept of Clebsch-Gordan coefficients.

Space Groups,This chapter focuses on space groups which result from combining rotational symmetries in solids with the translational symmetry. These are obviously the maximum symmetry groups of crystals.
