Abstract
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.
