Abstract
Long-wavelength charge fluctuation models are constructed for 1:2:3 superconductors. These include planar plasmons (ω∼q) plus numerous acoustical plasmons (ω∼q). We show that these modes do not cause pairing of electrons into a superconductor state. Our results rule out interlayer and intralayer pairing by long-wavelength charge fluctuations.
