Spin-charge separation at small lengthscales in the 2D t-J model
arXiv:cond-mat/9404045 · doi:10.1103/PhysRevB.50.11313
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 {\it et al.} indicates spin-charge separation at small lengthscales.
