| Course description |
|
The purpose of advanced superconductivity is to understand the physics and phenomena of superconductivity. Superconductivity is a phenomenon characterised by the loss of electrical resistance, Superconductivity was discovered in 1911 by Kamerlingh Onnes in Holland. It took almost 50 years to reach the microscopic understanding of this phenomenon by Bardeen-Cooper-Shrieffer (BCS) in 1957. As expected by this long history, it is not easy to imagine the BCS state, the essence of the theory. This is not only due to the advanced quantum mechanics based on the second quantization (quantum field theory) required but also due to the concept of macroscopic quantum state. The lecture of advanced superconductivity aims at understanding the phenomena and basic physics of superconductivity. |
| Expected Learning |
|
The goals of advanced superconductivity are (1) to understand the phenomnological Ginzburg-Landau theory of superconductivity, (2) to understand the basics of the micoscopic BCS theory of superconductivity. |
