Exact eigenstates of non-frustration-free quantum many-body systems are constructed via a local error cancellation matrix-product ansatz.
Recurrence plots of two-site correlations in the quenched 1D transverse-field Ising model transition from periodic to multiscale structures across the ferromagnetic-to-paramagnetic transition, and recurrence quantifiers recover the critical field strength in an unsupervised manner.
Asymptotic quantum many-body scars in SU(N) Hubbard chains are realized explicitly as gapless magnons of an embedded SU(N) ferromagnetic Heisenberg parent Hamiltonian.
A (1+1)D SU(2) lattice gauge theory with dynamical matter exhibits ergodic, fragmented, and disorder-free many-body localized phases under non-Abelian gauge constraints, with the localized regime preserving spatial inhomogeneities via sector superpositions.
Symmetric superpositions of antipodal triplet states produce exact zero-energy eigenstates in non-integrable spin Hamiltonians that are scars with tunable entanglement from volume to area law.
