    • Beyond the single-band approximation, Wannier-Stark states are actually resonances because of Zener tunneling ZT and BOs are thus damped, see, for instance, 10.1016/S0370-1573(02)00142-4

Korsch, Phys. Rep. 366, 103 (2002). However, in this work we assume that ZT is negligible. 10.1016/S0370-1573(02)00142-4

    • This property follows readily from the relation S (κ) ∼ n cn exp (-inκa) between Bloch (S) and Wannier (cn) amplitudes of the state vector Ψ. The condition n | cn | 2 < ensures the convergence of the series defining S (κ) in the entire Brillouin zone.

    • As the chain is terminated at n=N=73, to avoid reflections due to array truncation, smoothly absorbing boundary conditions have been assumed on the right-hand side of the integration domain.
