the spectral function and the power-law behavior of the spectral function

Caption

 (a) The energy dependence of the spectral function at k = 0.1kF under moderate strength (γ = 4.0). The black dashed and dotted lines respectively indicate the boundaries of type-I and type-II excitation spectra. (b) The power-law behavior of the spectral function near the four boundaries. The red and blue circles represent the calculated results, and the black dashed lines represent the fitted power-law curves.
