| 摘 要： | 在一定温度下的掺杂铜氧化合物高温超导体中,空穴间的强库仑关联作用和对关联的竞争使得在一定温度下条纹相与超导相共存。从一个二维格点模型出发,重点研究自旋调制对条纹相的影响,利用Fortran程序计算出不同的序参量下的条纹结果并用Matlab画出相应的图形,分析不同的序参量对条纹的影响,并试图探讨条纹相和超导相之间的微妙关系。

| Abstract: | At some given temperature,the competition between the strong correlation and the paring coupling of holes in doped cuprates lead the coexisting phase of superconducting and stripe order.Using Fortran language,this paper work out the effects with the different order parameters,draw some pictures with Matlab,then we analysis the effects on the stripe.We tried to explore the delicate relationship of stripe phase and superconducting phase. |
