摘要：

The motion of holes on the triangular lattice is studied using the t-J model. Within the Born self-consistent approximation and the exact Lanczos 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.
