摘要
We consider the two-dimensional t-J model with a hole on the Neel background. Based on variational method approach, the vertex function for interaction of a hole with long-wave-length magnons is calculated. The approach is justified at least for 0 less-than-or-equal-to t/J less-than-or-equal-to 4-5.
