Qualitative Analysis Of Superconductivity

This paper provides an all-encompassing view of superconductivity, starting with the quantum mechanical and solid-state basis of the phenomena. It has historical accounts about the discovery of superconductivity and introduces the basic quantum concepts such as wave function, quantum state, and the Schrödinger equation. The topics then switch to crystal structures, band theory, and electron pairing in superconductors. Rather than mathematics, it is more about qualitative understanding and has included experimental methods and applications, from MRI to maglev, challenges today, and the brighter future of high-temperature superconductors.
