|B||Appendix B Survival kit for superconductivity|
This survival kit is intended to provide basic knowledge of superconductivity necessary for understanding the material of the book. We recommend Refs. , , and  to the reader who wishes to acquire a deeper understanding of superconductivity concepts.
B.1 Basic facts
• Below a certain temperature Tc (the superconducting transition temperature), the electrical resistance of some metals vanishes. In particular, the most commonly used superconductors are aluminum and niobium; alkali, noble, and magnetic metals never become superconducting. The highest transition temperature found ...
