Some parts at 20 degrees Kelvin and Other at Room Temperature and the Whole Wire still Superconducts
According to Yonatan Dubi and Massimiliano Di Ventra of the University of California, San Diego. They have calculated that provided some points along the wire’s length stay below the threshold temperature, the material will superconduct. For this to work, the wire’s surface must be extremely clean, allowing electrons to move freely and spread along the …
