Phase diagrams of systems with two coupled order parameters
D. Nicolaides, A. A. Lisyansky
Within the framework of an exactly solvable model, which takes into account the interaction of fluctuating modes with equal and opposite momenta, we consider phase diagrams in syst…
Resonant tunneling of electromagnetic waves through polariton gaps
Lev I. Deych, D. Livdan, A. A. Lisyansky
We consider resonant tunneling of electromagnetic waves through an optical barrier formed by dielectric layers with the frequency dispersion of their dielectric permiability. The f…
Local polariton states in impure ionic crystals
V. S. Podolsky, Lev I. Deych, A. A. Lisyansky
We consider the dynamics of an ionic crystal with a single impurity in the vicinity of the polariton resonance. We show that if the polariton spectrum of the host crystal allows fo…
Random path averaging in multiple scattering theory
V. S. Podolsky, A. A. Lisyansky
A new method of path averaging for waves propagating in a random dilute system of identical scatterers is developed. The scattering matrix of such a system is calculated. The metho…
Wave localization in generalized Thue-Morse superlattices with disorder
Lev I. Deych, D. Zaslavsky, A. A. Lisyansky
In order to study an influence of correlations on the localization properties of classical waves in random superlattices we introduce a generalized random Thue-Morse model as a fou…
Local Polariton States in Polar Crystals with Impurities
Lev I. Deych, Alexander A. Lisyansky
We show that an impurity embedded in an ionic crystal can give rise to a novel kind of local states. These states exist within a polariton gap of a material and are a mix of excita…
