Universality of Abelian and non-Abelian Wannier functions in generalized one-dimensional Aubry-André-Harper models
Within a Dirac model in 1+1 dimensions, a prototypical model to describe low-energy physics for a wide class of lattice models, we propose a field-theoretical version for the representation of Wannier functions, the Zak-Berry connection, and the geometric tensor. In two natural Abelian gauges we pre...
