Abstract We present a study of hybrid light–matter excitations in cavity QED materials using the Dicke–Ising model as theoretical framework. Leveraging linear response theory, we derive exact system thermodynamic limit. Our results demonstrate that can localize spin excitations, leading to formation bound polaritons, where acts an impurity two-excitation band, localizing spin-wave pairs around single-spin domains. condition for existence these states and discuss its satisfiability different regimes. Finally, show effects persist finite systems exact-diagonalization calculations.
