      abstract     = {We present an ab initio analysis of a continuous
                      Hamiltonian that maps into the celebrated Haldane model. The
                      tunneling coefficients of the tight-binding model are
                      computed by means of two independent methods—one based on
                      the maximally localized Wannier functions, and the other
                      through analytic expressions in terms of gauge-invariant
                      properties of the spectrum—that provide a remarkable
                      agreement and allow one to accurately reproduce the exact
                      spectrum of the continuous Hamiltonian. By combining these
                      results with the numerical calculation of the Chern number,
                      we are able to draw the phase diagram in terms of the
                      physical parameters of the microscopic model. Remarkably, we
                      find that only a small fraction of the original phase
                      diagram of the Haldane model can be accessed, and that the
                      topological insulator phase is suppressed in the deep
                      tight-binding regime.},
