Abstract

A recent theory of the resonant neutron scattering peaks in YBCO superconductors predicts the existence of a sharp spin-triplet two-particle collective mode (the “ π resonance”) in the normal state. In this paper, we propose an experiment in which the π resonance could be probed directly in a two-particle tunneling measurement.
