Cooper (b. 1930), and John Robert Schrieffer (1931–2019), U.S. physicists, who described the theory in 1957 ( Physical Rev. 108 1175)] Physics attributive designating a theory of superconductivity which attributes the phenomenon to the collective behaviour of weakly bound pairs of electrons (Cooper pairs), which are not scattered by defects, phonons, etc., and hence experience zero resistance; relating to or conforming to this theory.The theory also finds applications in nuclear physics. ΚΠ 1958 Physica 24 Suppl. S147 (heading) The interaction in the BCS theory of superconductivity. 1958 C. G. Kuper in Physica Jan. 304 Recently Bardeen, Cooper and Schrieffer (hereafter quoted as BCS) have proposed a theory in which the wave functions contain electron correlations.] 1968 C. G. Kuper Introd. Theory Superconductivity xv. 258 The Yukawa force between nucleons has a pairing part, and the methods of the BCS theory are applicable. 1994 New Scientist 17 Sept. 32/2 The BCS model says that a travelling electron can induce vibrations called phonons, of atoms or of the lattice that makes up the crystal. 1996 F. Yang & J. H. Hamilton Mod. Atomic & Nucl. Physics xi. 508 The BCS theory of superconductivity was subsequently introduced into nuclear physics to explain nucleon pairing. 2009 Sci. Amer. (U.K. ed.) Aug. 63/2 In BCS materials, the Cooper pairs have so-called spherical symmetry. < as lemmas |
