This phenomenon, described by BCS theory and discovered by Heike Kamerlingh Onnes, is exemplified by materials like YBCO.
Coleman and Weinberg developed a four-dimensional extension to a theory of this phenomenon whose namesake parameter is the penetration depth over coherence length. That theory, named for (*) Ginzberg and Landau, is contrasted with the microscopic theory of this phenomenon, which focuses on the condensation of electrons into phonon-exchanging pairs. This phenomenon, described by BCS theory and discovered by Heike Kamerlingh Onnes, is exemplified by materials like YBCO. For 10 points, name this low-temperature phenomenon, the onset of zero resistance.
