导出了量子无序系统的一种新的超对称表象。这种表示是精确的,并且与非线性sigma模型的表示是对偶的。通过计算一维安德森模型的波函数振幅分布,对新的形式进行了检验。在带中心E=0附近检测到与粗线分布的偏差。
A new super-symmetric representation for quantum disordered systems is derived. This representation is exact and is dual to that of the nonlinear sigma-model. The new formalism is tested by calculating the distribution of wave function amplitudes in the 1d Anderson model. The deviation from the distribution found for a thick wire is detected near the band center E=0.
