摘要：
Commensurate flux phases are investigated on a finite 4 × 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. © 1990.
