Query: Ginzburg-Landau theory of an RVB superconductor   We present a Ginzburg-Landau formulation of the bosonic resonating valence
bond (RVB) theory of superconductivity. The superconducting order parameter is
characterized by phase vortices that describe spinon excitations and the
transition to the superconducting state occurs when such phase vortices
(un)bind. We show that the boson RVB theory always leads to hc/2e flux quanta
and that the presence of a trapped spin-1/2 moment inside a vortex core gives
rise to observable consequences for the low temperature field dependent
specific heat. We also show that the cores of magnetic fluxoids exhibit
enhanced antiferromagnetic correlations.
