Dataset: Dark Impurity States in Lattice Systems

The data associated with each figure are organized as follows. Figure 2: Two-body spectrum. The columns are arranged as UI/tb, E1, E2, ..., EN. Figure 3: Spectral function. Separate files provide the values corresponding to the x- and y-axes, namely UI and frequency, respectively. Figure 4: Many-body spectrum. The columns are arranged as UI/tb, E1, E2, ..., EN. Figure 5: Wave function in momentum space and correlation function. The wave-function data include the momentum-space grid in both the px and py directions, together with the real and imaginary parts of the wave function. The correlation function is provided in a separate file containing the corresponding x and y values in momentum space. The codes used to generate the figures are available upon request.
