Coexistence of the Bandcount-Adding and Bandcount-Increment Scenarios

Figure 10

Numerically calculated bandcount diagram in the 2D parameter space for 𝑎=0.2, 𝑏=−1.794⋯−1.49, 𝜇=0.468⋯0.536. The bandcount-adding region 𝑄⁷_ℒℛ4 is shown enlarged. The bandcount doubling region 𝑄¹⁷_{ℒℛ2ℒℛ6} is visible in the middle. The first three regions of both nested bandcount-adding structures to the left and to the right of 𝑄¹⁷_{ℒℛ2ℒℛ6} are labeled. The second bandcount doubling region 𝑄³⁷_{ℒℛ6ℒℛ4ℒℛ2ℒℛ4} is also labeled. The rectangle in Figure 8 shows where this figure is located in the overall bandcount-adding scenario. The analytical Figure 11 corresponds to this image.
