摘 要：Universality class of wave chaos emerges in many areas of science,such as molecular dynamics,optics,and network *** this work,we generalize the wave chaos theory to cavity lattice systems by discovering the intrinsic coupling of the crystal momentum to the internal cavity *** cavity-momentum locking substitutes the role of the deformed boundary shape in the ordinary single microcavity problem,providing a new platform for the in situ study of microcavity light *** transmutation of wave chaos in periodic lattices leads to a phase space reconfiguration that induces a dynamical localization *** degenerate scar-mode spinors hybridize and non-trivially localize around regular islands in phase *** addition,we find that the momentum coupling becomes maximal at the Brillouin zone boundary,so the intercavity chaotic modes coupling and wave confinement are significantly *** work pioneers the study of intertwining wave chaos in periodic systems and provide useful applications in light dynamics control.
