Description
This talk starts from Fock-space cages, which are localized many-body eigenstates stabilized through destructive interference in the state space. I then turn to the spectral setting that makes such states possible: constrained spin chains with an exponentially large manifold of exact zero modes, a hard gap around zero energy, and otherwise chaotic bulk dynamics described by chiral random matrix theory. This provides a simple setting in which Fock-space localization and quantum chaos coexist.
