COURSE AIMS AND OBJECTIVES: Introduction to basic techniques of obtaining low temperatures, the unique properties of helium (superfluidity) and basic characteristics and possible applications of superconductivity.
COURSE DESCRIPTION AND SYLLABUS:
1. Obtaining low temperatures (principles of liquefaction, liquid nitrogen and helium).
2. Working with cryogenic liquids (cryostats, heat losses).
3. Methods of measurement of low temperatures.
4. The properties of He4 and He3 (superfluidity).
5. The methods of obtaining temperatures below 1 K (He3 cryostat, He3 - He43 dilution cryostat).
6. Superconductivity (basic properties: the ideal conductivity, Meissner effect).
7. Characteristics of low temperature and high-temperature superconductors.
8. London's theory, thermodynamic properties.
9. Basics of Ginzburg-Landau and Bardeen-Cooper-Schrieffer model.
10. Macroscopic and microscopic application of classical and high-temperature superconductivity (science, industry, medicine, electrical engineering, transport).
TEACHING AND ASSESSMENT METHODS:
Students' obligations during classes: Attending lectures and tutorials, practical work in the low-temperature laboratory, undertaking a study project.
Signature requirements: Attendance at 70% of lectures and presenting the results of study project.
Taking of exams: The exam consists of the presentation and submission of the results of the study project and of the final exam in the oral form. Final grade is a combination of grades obtained for the study project and the final exam.
