Breakdown of the Peierls substitution for the Haldane model with ultracold atoms
Julen Ibañez-Azpiroz, Asier Eiguren, Aitor Bergara +2
We present two independent calculations of the tight-binding parameters for a specific realization of the Haldane model with ultracold atoms. The tunneling coefficients up to next-…
Self-consistent tight-binding description of Dirac points moving and merging in two dimensional optical lattices
Julen Ibañez-Azpiroz, Asier Eiguren, Aitor Bergara +2
We present an accurate ab initio tight-binding model, capable of describing the dynamics of Dirac points in tunable honeycomb optical lattices following a recent experimental reali…
Tight binding models for ultracold atoms in honeycomb optical lattices
Julen Ibañez-Azpiroz, Asier Eiguren, Aitor Bergara +2
We discuss how to construct tight-binding models for ultra cold atoms in honeycomb potentials, by means of the maximally localized Wannier functions (MLWFs) for composite bands int…
