Statistics of conductances and subleading corrections to scaling near the integer quantum Hall plateau transition

Statistics of conductances and subleading corrections to scaling near the integer quantum Hall plateau transition

We study the critical behavior near the integer quantum Hall plateau transition by focusing on the multifractal (MF) exponents Xq describing the scaling of the disorder-average moments of the point contact conductance T between two points of the sample, within the Chalker-Coddington network model. Past analytical work has related the …
