The AQS model \(\pmb{\{H_{1}^{\mathrm{per}}, C_{z}(2,6)\}}\) evaluated with 10 spins. (a) Eigenvalues of the FIM at different values of \(B^{0}\). The largest eigenvalue is shown in color for zero temperature (ground state) and intermediate temperature (\(\beta=1\)), whereas the insignificant ones are shown in gray. (b), (c) Composition of the influential CPD in terms of the original underlying Hamiltonian parameter variations. The data points (which are entries of the principal eigenvector) are labeled by the parameter variation that they multiply to form the CPD, see Eq. (3).
