FY548: Solid state physics
Comment
The course is co-taught with FY837 Solid State Physics.
Entry requirements
Academic preconditions
Students taking the course are expected to:
- Have knowledge of basic classical mechanics, thermodynamics, electromagnetism, quantum mechanics, and statistical mechanics
- Be able to use elementary mathematics to handle model descriptions based on physical laws.
Course introduction
The course gives an introduction to the physics of condensed matter with emphasis on crystalline materials. The student should after the course be able to explain on a quantum mechanical basis, theoretical models for the properties of solids and be able to apply these models to calculate mechanical, thermo-dynamical and electronic properties of matter. The course provides a basis for understanding the scientific literature on novel nano-structured materials and to further studies in materials science, nano-technology and bio-physics.
The course builds on the knowledge acquired in the courses FT504: Electromagnetism and Optics (10 ECTS), FY546 Advanced Mechanics and Relativity Theory (10 ECTS), FY544 Quantum mechanics I (5 ECTS), FY547 Quantum mechanics II (5 ECTS) and FY550 Statistical physics (5 ECTS), and gives an academic basis for writing a bachelor and a master thesis in condensed matter physics.
In relation to the competence profile of the degree it is the explicit focus of the course to:
- Give the competence to handle complex problems and independently take part in interdisciplinary work and identify needs for and structure of own learning.
- Give skills to apply physical principles and mathematical tools to formulate and evaluate physical models.
- Give knowledge and understanding of the properties of condensed materials.

Teaching Method
At the faculty of science, teaching is organized after the three-phase model ie. intro, training and study phase.
- Intro phase (lectures) - 30 hours
- Training phase: 20 hours, including 20 hours tutorials
Activities during the study phase:
- Self-study of the textbook and notes
- Written assignments
- Working with a project which involves preparation of an oral presentation.
- Independent work with the topics in the intro- and skills training phase
- Preparation for the exam
