Course overview and goals
In crystal physics, crystals are considered as an anisotropic medium from a macroscopic point of view. The concept of tensors is important for discussing the physical properties of crystals. After giving an overview of crystal physics, we discuss transformations and second-order tensors. Next, we consider the anisotropy of paramagnetic and diamagnetic susceptibility and electric polarization as the characteristics of the equilibrium state of crystals. The point group of crystals and symmetry operations are also explained.
Course description and aims
By the end of this course, students will be able to:
1) Understand that the basic structure of materials are periodic arrangements of atoms.
2) Explain that the symmetry and macroscopic properties of materials are strongly interconnected.
Keywords
Crystals, lattice, point group, symmetry, tensors

Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook(s)
J. F. Nye “Physical Properties of Crystals: Their Representation by Tensors and Matrices” (Oxford University Press)
Reference books, course materials, etc.
We Use lecture materials as needed.
