PPT-Superconductivity

By Shruti Sheladia Garrett M Leavitt Stephanie Schroeder Christopher Dunn Kathleen Brackney Levitation of a magnet above a high temperature superconductor illustrating the . The interplay of superconductivity and disorder has intrigued scientists for several decades Disorder is expected to enhance the electr ical resistance of a system whereas superconductivity is associated with a zeroresista nce state Although superco These are meta llic materials with very large electronic effective mass 100 or more times larger than the bare electron mass arising from an antiferromagnetic interaction between c onduction electrons and the local magnetic moments Kondo effect resi Chapter 11). BCS theory has established that superconductivity in conventional materialsarises from interactions of the conduction electrons with the vibrations of the atoms.This interaction enables a The University of Tennessee (UT).
