M. Azzouz et T. Dombre, MOTION OF HOLES ON THE TRIANGULAR LATTICE STUDIED USING THE T-J MODEL, Physical review. B, Condensed matter, 53(1), 1996, pp. 402-409
The motion of holes on the triangular lattice is studied using the t-J
model. Within the Born self-consistent approximation and the exact La
nczos diagonalization, the single-hole physics is first analyzed. Then
the spiral phase theory of Shraiman and Siggia is used to investigate
the case of a finite density of holes.
