我们报告了整数量子霍尔效应 Chalker-Coddington 模型临界指数的估计 $\ensuremath{\nu}=2.593$ [2.587,2.598]，该指数明显大于之前的数值估计，并且与实验不一致。这表明非相互作用电子模型无法解释整数量子霍尔效应的关键现象。
We report an estimate $\ensuremath{\nu}=2.593$ [2.587,2.598] of the critical exponent of the Chalker-Coddington model of the integer quantum Hall effect that is significantly larger than previous numerical estimates and in disagreement with experiment. This suggests that models of noninteracting electrons cannot explain the critical phenomena of the integer quantum Hall effect.
