    • The use of off-resonant walking waves, instead of standing waves, presents the advantage that there is no need to control the position of the ion chain with respect to the applied wave.

    • There is also an error term proportional to the transverse magnetic field Herr =2ih jnα ξ jn α a nα † σjy +H.c. However, it gives a negligible contribution for the range of parameters that we are interested in h J2, J3, which leads to insignificant corrections of the order O (Fx6 / δx6).

    • In order to neglect the error term quadratic in phonon operators, the ion chain should be cooled down to n̄ <0.1, which does not require spectral resolution of the different modes (i.e., kB T βω).
