A quantum Hall system is governed by a magnetic Schrodinger operator on the 2D sample manifold. Remarkably, its conductance is always rounded off to an integer, and this spectral property withstands a huge range of geometric perturbations. This is an example of large-scale quantization, whose underlying mechanism comes from the growing mathematical field of large-scale index theory.
