The resonating valence bond–Luttinger liquid theory for the high-${\mathit{T}}_{\mathit{c}}$ normal state permits some predictions about the effect of superconductivity on two measures of the one-particle Green’s function: angle-resolved photoemission and tunneling for a high-${\mathit{T}}_{\mathit{c}}$–insulator–high-${\mathit{T}}_{\mathit{c}}$ junction. These are compared to preliminary experimental data.
