✦ Synopsis

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 shown to exhibit no effective hole-hole attraction in real space

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
