Engineering Superconductivity

Superconductivity has been known for over a century. The liquefaction of Helium opened a whole new branch of experimental and theoretical work in low temperature physics. Since those days the discovery of High Temperature and Unconventional superconductors has been on the focus of a large amount of scientific research, with an exponentially growing spectra of applications for technologies. Superconducting technology has the potential for future smart grid technologies. A combination of superconductor materials, electrical engineering, cryogenic insulation, cryogenics and cryostats constitutes some of the most recognized applications so far implemented. We engage some aspects of superconductivity using a theoretical and applied approaches, then several experimental set ups and results are included with potential applications. Hope this book can guide the reader into this promising field. This book entitled Engineering Superconductivity covers some developments in these areas, making it essential for future applied superconductivity in electrical engineering and even in biomedicine. Content coverage of the book is as follows. First chapter gives an overview of recent advances in novel superconductors and second chapter presents a brief review on the investigation of the electronic structure and superconductivity of the FeSe superconductor and related systems. In third chapter, triplet superconductivity in a nutshell were studied, and fourth chapter discusses about superconductivity, charge orderings, magnetism, and their phase separations in the ground state of lattice models of superconductor with very short coherence length. Fifth chapter focuses on predicting unconventional high temperature superconductors in trigonal bipyramidal coordinations. Sixth chapter deals with electronic energy levels in high-temperature superconductors. Seventh chapter explores on experimental demonstrations of high-Q superconducting coplanar waveguide resonators. The main objective of eighth chapter is to study the electronic structure of Nb3Al/Nb3Sn using the state of the art first principle method. Ninth chapter deals with magnetoresistance oscillations in La-based metallic glass. Tenth chapter provides a novel superconducting quantum interference device for biomagnetic measurements. Eleventh chapter focuses on preparation of Nb3Al superconductor by powder metallurgy and effect of mechanical alloying on the phase formation. Twelfth chapter highlights on exploration of new superconductors and functional materials, and fabrication of superconducting tapes and wires of iron pnictides. In thirteenth chapter, competition between the superconductivity and nematic order in the high-Tc superconductor were studied. Fourteenth chapter presents interplay and competition between superconductivity and charge orderings in the zero-bandwidth limit of the extended Hubbard model with pair hopping and on-site attraction. Fifteenth chapter covers superconductivity in Fe and As based compounds.
