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.

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%.
