Full Description
This book effectively explains key concepts, providing shortcuts to understanding each topic and enabling readers to quickly grasp the underlying principles. It is based on a course taught by the author and is primarily aimed at undergraduate and graduate engineering students.
This second, enlarged edition offers a novel, concept-driven approach to superconducting electronics, utilizing COMSOL Multiphysics to provide intuitive insight into fundamental principles.
The book is divided into three main parts. The first part introduces key topics in superconductivity, illustrated with COMSOL simulations based on the time-dependent Ginzburg-Landau equations, while avoiding deep mathematical derivations. It includes numerous worked examples and problem sets with tips and solutions.
The second part is more advanced and follows a more conventional approach, providing detailed derivations of the fundamental equations from first principles. It covers advanced topics such as the BCS-Gor'kov-Eliashberg framework for equilibrium superconductivity, the derivation of kinetic equations for nonequilibrium superconductors, and the derivation of time-dependent Ginzburg-Landau equations used in the first and third parts.
The third part, new to this edition, presents more realistic COMSOL examples based on the advanced theoretical foundation developed in the second part. It addresses electric transport in arbitrarily shaped superconductors, proximity effects in dynamic regimes, and voltage- and current-biased weak links. Additional topics include a more general treatment of phase-slip centers and the analysis of the Aharonov-Bohm effect and related macroscopic quantum phenomena in superconductors.
Supported by an extensive online library of COMSOL Multiphysics model files and animations, the book serves as an accessible introduction for beginning researchers and readers with a less formal background in physics and mathematics, while also providing sufficient depth for those wishing to explore the subject more rigorously.
