Current Loops (image) University of California - Riverside Caption A 1996 theory by UCR's Chandra Varma notes that in copper oxide materials superconductivity is associated with the formation of a new state of matter in which electric current loops form spontaneously, going from copper to oxygen atoms and back to copper. Recently, a French-German team of experimental scientists directly observed the current loops. Credit C.
