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
1.3. demonstrate a thorough knowledge and understanding of the most important physics theories (logical and mathematical structure, experimental support, described physical phenomena
1.6. demonstrate knowledge and understanding of new insights into contemporary physics and chemistry teaching methods and strategies
2. APPLYING KNOWLEDGE AND UNDERSTANDING
2.4. recognize and follow the logic of arguments, evaluate the adequacy of arguments and construct well supported arguments
2.5. prepare and perform classroom physics and chemistry 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:
1. work in low-temperature laboratory,
2. plan the manufacturing of parts of the apparatus used for demonstration experiments in low-temperature physics,
3. perform and interpret demonstration experiments in low-temperature physics,
4. demonstrate a broad understanding of the phenomenon of low-temperature physics,
5. demonstrate knowledge and understanding of superconductivity and superfluidity.
COURSE DESCRIPTION:
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]
Superconductivity (physical characteristics, theoretical models, applications) [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%.
