BCS wavefunctions are constructed as many-body scars in fermionic models whose scar-subspace dynamics coincide with the BCS mean-field Hamiltonian, protecting them from thermalization.
Fock space cages from destructive interference in kinetically constrained models yield localized many-body eigenstates and non-ergodic dynamics by treating Fock space as a graph of bitstring states.
