Abstract
The one-dimensional t-J model is investigated by using variational wave functions for strongly correlated regimes. The Gutzwiller-Jastrow-type trial state has been studied extensively but it does not have spin-charge separation explicitly. On the other hand, another type of variational wave function is considered, which has the spin-charge separation and is easy to extend to higher dimensions. This trial state has spinless fermions as the charge degrees of freedom and a resonating-valence-bond state as the spin degrees of freedom.
