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.
