Criticality in the Integer Quantum Hall Effect
arXiv:cond-mat/9703026 · doi:10.1142/9789812819444_0005
Abstract
We review some elementary aspects of the critical properties of the series of metal-insulator transitions that constitute the integer quantum Hall effect. Numerical work has proven essential in charting out this phenomenon. Without being complete, we review network models that seem to capture the essentials of this critical phenomenon.
