Description:
Author(s): Alexander Lau, Carmine Ortix, and Jeroen van den Brink The Hofstadter model is a simple yet powerful Hamiltonian to study quantum Hall physics in a lattice system, manifesting its essential topological states. Lattice dimerization in the Hofstadter model opens an energy gap at half filling. Here we show that even if the ensuing insulator has a Chern num… [Phys. Rev.
