摘要
用Slave-Fermion方案研究低温小掺杂下强关联Hubbard模型的磁性和反铁磁序的问题。比较Slave-Boson方案与Slave-Fermion方案,表明二种方案的结果大致相同,但用Slave-Fermion方案能更好地解释低温出现的反铁磁长程序。
The statistics of the Spinons and Holons in strongly correlated 2D-Hubbardmodel is studied.The static magnetic susceptibility and the gap equation of Spinons arecalculated by using the slave-Ferlnion method.We compare the results between slave-Fermion and slave-Boson,and believe that the slave-Fermion method can betterexplain the AFMLR of MT_cSC in low temperature.
