The term "superconductivity" is generally associated with the image of an electric current flowing without resistance, but in fact, it is a novel state of physics concept. It was from superconductivity that Yoichiro Nambu arrived at the concept of "spontaneous symmetry breaking," which led to the Nobel Prize. This book is a textbook that has been extensively expanded and revised with a new title, taking into account various developments in this field since the author published "Introduction to Superconductivity" in 2009, and will be a useful aid, for example, to solid state physics classes.
One revolution in superconductivity was the discovery of high-temperature superconductivity in the 1980s, and the mechanism of superconductivity is completely different from the conventional one (originating from the Coulomb repulsion interaction between electrons), which is conceptually interesting. Starting from the standard theory of conventional superconductivity, this book describes in detail the innovative developments in high-temperature superconductivity in iron and nickel compounds, following the copper-based superconductors, in the past 15 years. In addition, near-room-temperature superconductivity in hydrogen compounds and graphene superconductivity have also been produced, and these are explained from the characteristics of the materials to the theoretical picture. A new development is superconductivity in non-equilibrium, exemplified by the Higgs mode. The Higgs was discovered in 2012 as an elementary particle in an accelerator, and there exist excitation modes similar to the Higgs in superconductors closely related to the Nambu theory, which have recently become a hot topic. In addition, we have enhanced the "Column" column, which corresponds to a chat in a classroom lecture. I always think that the study of science is like climbing a mountain whose peak gets higher and higher as you go up, and I hope this book will help you experience this in superconductivity as well.
