Query: Parallels Between Quantum Antiferromagnetism and the Strong Interactions   I argue that there is a connection between quantum antiferromagnetism and the
strong interactions. The underlying idea is that the t-J Hamiltonian and other
models commonly studied in the context of cuprate superconductivity are near a
quantum critical point at which quark-like objects and gauge fields with which
they interact become the true elementary excitations at low energy scales. Away
from the critical point these bind at low energy into familiar collective modes
of various ordered states. As evidence I cite the ``semiconducting'' behavior
of the f-sum rule at low doping, large-scale structure in the electron
propagator, disappearance of the quasiparticle pole at small values of J/t,
string resonances above the quasiparticle pole, and the physical similarity of
the alleged quark-like objects to the spinon and holon excitations of
1-dimensional spin-1/2 antiferromagnets.
