Course description and aims
When superconductors are cooled to extremely low temperatures, the electrical resistance goes to zero and they show electrical and magnetic properties that are not seen in usual metals. Students will learn that the reason lies in quantum nature appearing on a macroscopic scale. In this course, after getting an overview of various properties of superconductivity, students will study superfluidity and Bose-Einstein condensation, the macroscopic description of superconductivity called the GL theory, the microscopic one called the BCS theory, electrodynamics of superconductivity, magnetic properties, such as, quantized flux in type-II superconductors: they will also study unconventional superconductivity and the latest topics related to superconductivity.
Student learning outcomes
[Learning outcomes] Students will learn fundamentals of physics on superconductivity, which is a macroscopic quantum phenomenon that appears at low temperatures.
[Theme] This course focuses on unusual electrical, magnetic, and thermodynamic properties that superconductors show at low enough temperatures. Students are expected to understand the underlying physics and learn how to describe them.
Keywords
Bose-Einstein condensation, zero resistance, Meissner effect, macroscopic quantum phenomenon, London equations, GL theory, BCS theory, quantized flux, type-I/type-II superconductors, Josephson effect, SQUID, unconventional superconductors
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | ✔ Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
Handouts will be distributed at the beginning of each class. Students are given exercise problems related to the lecture to better understand the contents. The midterm exam (50 min) is scheduled during the regular lecture period.
