Using a Scanning Microscope to Study Cooperative Rates

A coop rate called Bismuth, strontium, calcium, copper oxide had a peculiar feature that made their dream experiment possible. In Bisco, surrounding sheets of atoms squeezed the layers of copper and oxygen atoms into a wavy pattern. This varies the distance between certain atoms, which in turn affects the energy required to hop. The relationship between hopping energy and coop repair density closely matched a numerical prediction from 2021 by Trimblay and his colleagues. It strongly implies that super exchange is the superglue enabling high-temperature superconductivity.
