Models for the integer quantum Hall effect: the network model, the Dirac equation, and a tight-binding Hamiltonian
We consider models for the plateau transition in the integer quantum Hall effect. Starting from the network model, we construct a mapping to the Dirac Hamiltonian in two dimensions. In the general case, the Dirac Hamiltonian has randomness in the mass, the scalar potential, and the vector potential....
