Figure 3: Numerically decomposed contributions in the excitation spectrum and number distribution.
(a) Contributions to the spectrum from the SF and NF components and (b) atom distributions in the optical lattice (VL=5Er). The blue and red solid lines correspond to the SF and NF components, respectively, and the black lines are their sum. The green dashed line indicates the calculation result, which includes up to the first-order sum rule relation (see the text). The arrows in a labelled SFα, NFα m and NFα indicate the corresponding resonance peaks, where α and m are described in equations (8) and (9), respectively. The grey circles denote the same data shown in Fig. 2 for comparison.
