ARPES, Neutrons, and the High-$T_c$ Mechanism

Abstract

Extensive ARPES and low-energy inelastic neutron scattering studies of cuprate superconductors can be successfully described using a weak-coupling theory in which quasiparticles on a square lattice interact via scalar and spin-dependent effective interactions. In this article we point out that in Bi${}_2$Sr${}_2$Ca${}_{1-x}$Y${}_x$Cu${}_2$O${}_8$ (Bi2212) both probes are consistent with dominant near-neighbour Heisenberg interactions. We discuss the implications of this finding for the mechanism of high-$T_c$ superconductivity.
