This phenomenon was surprisingly discovered in 1988 in BSCCO (“bisko”), thanks to the fact that copper has the strongest covalent bonding to oxygen among transition metals. For 10 points each:
[10e] Name this phenomenon exhibited by many cuprates above 77 Kelvin, making them “high-temperature” examples of materials displaying this phenomenon.
ANSWER: superconductivity [accept word forms like superconducting; accept high-temperature superconductors]
[10h] The formation of Cooper pairs in cuprates has been explained via this interaction, in which two cations in a crystal interact via an intermediate anion. The Goodenough-Kanamori rules dictate the character of this interaction based on orbital overlap.
ANSWER: superexchange [accept Kramers-Anderson superexchange]
[10m] This physicist modeled cuprate superconductivity using resonating valence bond theory. Disordered systems display a form of “localization” named for this physicist.
ANSWER: Philip Anderson [accept Anderson localization]
