Each plot corresponds to one of the red lines in Fig. 6f, i. Ground state probabilities are calculated on these lines in J − G space for various methods in the main text. a k = 2 and G = 0.5. b k = 2 and J = 0. c k = 3 and G = −0.8. d k = 3 and J = −0.5. Vertical dashed red and black lines show where ground state energies and leading eigenvalues change, respectively. Background colors denote ground states in specific regions, with states and corresponding colors listed in the key.
