Figure 8From: Creation of two-dimensional Coulomb crystals of ions in oblate Paul traps for quantum simulations Spin-spin coupling versus distance for different detunings with DC voltages of and and different number of ions (different panels; (a) is and (b) is ) on a log-log plot. The colored lines are the fit to a power-law behavior . The detunings are to the blue of in units of .Back to article page
