12. In a variational approach [E.H. Rezayi and N. Read, Phys. Rev. Lett. 72, 900 (1994)], the ground-state wave function is exact for a certain class of local interactions for which (Formula presented). Thus, despite the interactions, the anisotropic system of CF here is absolutely equivalent to the isotropic one and is obtained from it by scale transformation (2). It can also be deduced that the anisotropy of fermionic one-particle Green function (and, if Landau-liquid description applies, the anisotropy of quasiparticle dispersion) gets weaker with increasing the range of the two-particle potential.
