Abstract

ARPES and low-energy inelastic neutron-scattering studies of cuprate superconductors are described using a weak-coupling theory in which quasiparticles on a square lattice interact via scalar and spin-dependent effective interactions. In this paper we point out that in underdoped Bi2212 both probes are consistent with dominant near-neighbor Heisenberg interactions. We discuss the implications of this finding for the mechanism of high-Tc superconductivity.
