## Commensurate flux phases are investigated on a finite 4 X 4 cluster in the 2 holes doped t-J model. Qualitative agreement is found with the Gutzwiller approximated results. in particular, the magnetic energy exhibits an absolute minimum when the flux equals exactly the filling. The CFP are show

We study new wavefunctions for generalized flux phases by the variational Monte Carlo method, in which the motion of holes produces additional phase factors besides those due to the motion of electrons. The phase factors cancel each other at some special electron densities and, as a result, there ar

A generalized slave-particle scheme is introduced to the t-J model including the non-local effects. We find a charge-spin decoupled state in which the non-local gauge fields play the rolcs of statistics-transmutation. As a result, the gauge fluctuation becomes massive and the electromagnetic respons
