摘要：

By expressing the Holstein-Primakoff transformation in a symmetric form, a new spin-polaron technique for treating the triangular-lattice antiferromagnet is developed. With this technique, we treat an extended t-J model, calculate the quasiparticle dispersion, and compare this dispersion with that obtained by another method.
