Exact eigenstates of multicomponent Hubbard models: SU(N) magnetic η pairing, weak ergodicity breaking, and partial integrability

We construct exact eigenstates of multicomponent Hubbard models in arbitrary dimensions by generalizing the \eta-pairing mechanism. Our models include the SU(N) Hubbard model as a special case. Unlike the conventional two-component case, the generalized \eta-pairing mechanism permits the construction of eigenstates that feature off-diagonal long-range order and magnetic long-range order....
