摘要：

A model of weakly interacting hole quasiparticles is proposed to describe the normal state of the high temperature superconductors. The effect of strong correlations is contained in the dispersion relation of the holes, which is obtained accurately using a numerical technique and the t-J model on 8 x 8, 12 x 12, and 16 x 16 clusters. Many-body effects induce anomalous quasiparticle flat bands similar to those observed in recent angle-resolved photoemission experiments. We also found that the Hall coefficient is in excellent quantitative agreement with experimental results for La2-xSrxCuO4. Several other ''anomalous'' features of the cuprates can be explained with this model.
