摘要:

在弱多重分形区域,我们微扰地计算了临界随机矩阵系综中波函数的多重分形谱。我们表明,在领先的顺序的频谱是普遍的,而高阶校正模型特定的。在幂律和超度规随机矩阵系综中得到了反常维数的显式结果。

英文摘要:

We calculate perturbatively the multifractality spectrum of wave-functions in critical random matrix ensembles in the regime of weak multifractality. We show that in the leading order the spectrum is universal, while the higher order corrections are model-specific. Explicit results for the anomalous dimensions are derived in the power-law and ultrametric random matrix ensembles.
