We consider projected wavefunctions for the 2D t-J model. For various wavefunctions, including correlated Fermi-liquid and Luttinger-type wavefunctions we present the static charge-charge and spin-spin structure factors. Comparison with recent results from a high-temperature expansion by Putikka et al. indicates spin-charge separation at small lengthscales.
