Local Chern marker of smoothly confined Hofstadter fermions
Local Chern marker of smoothly confined Hofstadter fermions
The engineering of topological non-trivial states of matter, using cold atoms, has made great progress in the last decade. Driven by experimental successes, it has become of major interest in the cold atom community. In this work we investigate the time-reversal invariant Hofstadter model with an additional confining potential. By …
