Title: Linear response theory and the universal nature of the magnetic excitation spectrum of the cuprates.

Abstract

Linear response theory, commonly known as the random-phase approximation (RPA), predicts a rich magnetic excitation spectrum for d-wave superconductors. Many of the features predicted by such calculations appear to be reflected in inelastic neutron-scattering data of the cuprates. In this paper, I will present results from RPA calculations whose input is based on angle-resolved photoemission data, and discuss possible relevance to inelastic neutron-scattering data of La{sub 2-x}Sr{sub x}CuO{sub 4} (LSCO), YBa{sub 2}Cu{sub 3}O{sub 6+x} (YBCO), and Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x} (Bi2212) in their superconducting and nonsuperconducting phases. In particular, the question of the universality of the magnetic excitation spectrum will be addressed.
