Superconductivity: Exploring the Future of Zero-Resistance Technologies

Superconductors: Fundamentals, Applications, and Beyond

Superconductors, with their remarkable ability to conduct electricity without resistance, have fascinated scientists and engineers since their discovery over a century ago. This preface aims to provide an overview of the content and scope of this book, intended for students, researchers, and professionals keen to understand and harness the extraordinary properties of superconducting materials.

Historical Context and Scientific Milestones

The phenomenon of superconductivity was first observed by Heike Kamerlingh Onnes in 1911 when he discovered that mercury exhibited zero electrical resistance at temperatures close to absolute zero. This groundbreaking discovery set the stage for a century of research, leading to the development of theories and materials that have expanded our understanding and application of superconductors. From the BCS theory proposed by John Bardeen, Leon Cooper, and Robert Schrieffer in 1957, which explained superconductivity in terms of electron pairs or "Cooper pairs," to the discovery of high-temperature superconductors in the 1980s, each milestone has brought us closer to practical and widespread use of these materials.

Purpose and Audience

The primary purpose of this book is to bridge the gap between theoretical knowledge and practical application, offering insights into how superconductors can revolutionize various fields. It is designed for a diverse audience, including undergraduate and graduate students in physics, materials science, and engineering, as well as researchers and industry professionals seeking a thorough understanding of superconductors.
