摘要：
We suggest compact anzats for the trial wave function of a hole on the Neel background. The energy and the wave function is calculated analytically using variational method. Comparison with computer simulation justifies suggested approximation at least at t/J less-than-or-equal-to 4-5. However it is possible that this approximation is valid for larger t as well.
