|Cooper pair (k'pər) Pronunciation Key
A pair of weakly bound electrons in a superconductor. Cooper pairs have the property of bosons and can thus reside together in a ground state. They are named after their discoverer, American physicist Leon N. Cooper (born 1930). See also Bose-Einstein condensate.
