Anderson is the only theorist who answers questions at a news conference at the 1987 March Meeting of the American Physical Society (the “Woodstock of Physics”) where most physicists learned details about the newly discovered high-temperature cuprate superconductors, which lose all resistance at temperatures not very far below room temperature. He had just proposed a radical non-BCS theory which attributed superconductivity in these materials to a “resonating valence bond” description of a doped Mott insulator using a model first proposed by John Hubbard. He spent the next twenty years trying to convince his colleagues of the correctness of this theory, with only limited success.

Spectral Anomaly

Spectral anomaly for interacting fermions is characterized by the spectral function A ([k − k F ], ω) satisfying the scaling relation A (Λy1 [k − k F ], Λy2 ω) =ΛyA A ([k − k F ], ω), where y1, y2, and yA are the exponents defining the universality class. For a Fermi liquid y1 = 1, y2 = 1, yA = −1; all other values of the exponents are termed anomalous. In this paper, an example for which y1 = 1, y2 = 1, but yA = α − 1 is considered in detail. Attractive interaction added to such a critical system leads to a novel superconducting state, which is explored and its relevance to high temperature cuprate superconductors is discussed.

P Type

Based (i) on data for the Pb 2 Sr 2 YCu 3 O 8 (PSYCO) homologues with Y replaced by R = Ce or R = Am, and (ii) on experimental facts for Nd 2-z Ce z CuO 4, we conclude that all the main high-temperature cuprate superconductors are p-type, and that very likely none are n-type.
