COURSE GOALS: Introduction of students to experimental and theoretical aspects of low-temperature physics. This course gives a comprehensive overview of the area, starting from the methods of obtaining low temperatures, working with cryogenic liquids, temperature measurements to theoretical models for the most important phenomena of low-temperature physics: superconductivity and superfluidity. This course prepares students for work in the solid state physics laboratory and introduces them to the theoretical concepts of the most important phenomena of low-temperature physics.
LEARNING OUTCOMES AT THE LEVEL OF THE PROGRAMME:
1. KNOWLEDGE AND UNDERSTANDING
1.2. demonstrate a thorough knowledge and understanding of the most important physics theories (logical and mathematical structure, experimental support, described physical phenomena);
1.4. demonstrate knowledge and understanding of new insights into contemporary physics teaching methods and strategies;
2. APPLYING KNOWLEDGE AND UNDERSTANDING
2.2. recognize and follow the logic of arguments, evaluate the adequacy of arguments and construct well supported arguments;
2.4. prepare and perform classroom physics experiments and interpret the results of observation;
4. COMMUNICATION SKILLS
4.2. present complex ideas clearly and concisely;
4.4. use the written and oral English language communication skills that are essential for pursuing a career in physics and education;
5. LEARNING SKILLS
5.1. search for and use professional literature as well as any other sources of relevant information;
LEARNING OUTCOMES SPECIFIC FOR THE COURSE:
Upon passing this course, students will be able to:
* work in low-temperature laboratory
* plan the manufacturing of parts of the apparatus used for demonstration experiments in low-temperature physics
* perform and interpret demonstration experiments in low-temperature physics
* demonstrate a broad understanding of the phenomenon of low-temperature physics
* demonstrate knowledge and understanding of superconductivity and superfluidity
Methods of obtaining low temperatures (T> 1 K) (principles of liquefaction, helium and nitrogen liquefiers) [6 hours]
Working with cryogenic liquids (cryostats, thermometry, losses) [6 hours]
The properties of He4 and He3 (superfluidity) [3 hours]
Methods of obtaining temperature <1 K (He3 cryostat, He3-He4 dilution cryostat, Pomeranchuk effect, methods of demagnetization) [6 hours]
Condensates and excitations, vortex and sounds in helium [8 hours]

Student seminars [8 hours]
REQUIREMENTS FOR STUDENTS:
Students must attend classes and prepare seminar papers and presentations. In the end, students take the oral exam.
GRADING AND ASSESSING THE WORK OF STUDENTS:
During the course, students present seminars, and at the end of the course, take the oral exam. Seminars contribute about 40% of the final grade, and the oral exam 60%.
