'This is an excellent introductory textbook on superconductivity. It starts with a description of the basic phenomena, follows the sequence of historical discoveries and describes the various models proposed to explain them and to predict new effects. From chapter to chapter, Roland Combescot exposes in simple and elegant terms the quantum subtleties of superconductivity, develops step-by-step the various theoretical approaches and illustrates them with deep physical interpretations of the equations. The connection between condensed matter and cold atom physics is particularly interesting, with an illuminating description of the cross-over between the BEC and the BCS regimes of degenerate fermionic gases. This development, which shows that similar phenomena occur in very disparate systems, illustrates the deep unity of physics. This textbook will interest readers familiar with basic quantum physics and curious to understand the theory of superconductivity, as well as those interested in its various technological applications. It is a simple and particularly clear introduction for undergraduate and graduate students. I believe that it will also serve as a useful guide for teachers of a field of physics which – having been active for more than a century – still raises unanswered questions and promises new surprises.'

Superconductivity is among the most exciting of quantum phenomena in condensed matter physics, and has important applications across science and technology, from fusion reactors to particle accelerators. This self-contained text provides a comprehensive account of the physical foundations of superconductivity and related recent developments in the field. Beginning with a detailed description of the BSC theory of superconductivity, the book then describes the subsequent successes of this landmark theory and proceeds to more advanced topics such as Josephson effects and vortices. The strong coupling theory of superconductivity is introduced in later chapters, providing a springboard to important current research on hydride superconductors, which have displayed very high critical temperatures. Recent manifestations of superfluidity in ultracold atoms physics are also described. This book will give readers a solid grounding in the theory and applications of superconductivity, and an appreciation of its broader importance in the field of modern condensed matter physics.
