Impurity-Induced Polaritons in a One-Dimensional Chain
A detailed analytical study of an impurity-induced polariton band arising inside a spectral gap between lower and upper polariton branches is presented. Using the microcanonical method, we calculate the density of states and the localization length of the impurity polaritons. Analytical results are compared with numerical simulations, and excellent agreement is found.
