Recent experiments in exciton-polariton systems have provided high-precision measurements of the value polariton-polariton interaction constant, which is a key parameter that governs nonlinear dynamics polariton condensates and potentially enables quantum correlated polaritons. Yet, until now, this has only been addressed theoretically using perturbative treatments or approximations do not incl...

Optical parametric oscillators (OPOs) have been widely applied in spectroscopy, squeezed light, and correlated photons, as well quantum information. Conventional OPOs usually suffer from a high power threshold limited by weak high-order nonlinearity traditional pure photonic systems. Alternatively, polaritonic systems based on hybridized exciton–photon quasi-particles exhibit enhanced optical d...

A bstract This study investigated the hybridization between an axion and plasmon polariton, attributed to coupling achieved by combining modified electrodynamics hydrodynamic approaches on a plasmon-polariton in graphene periodic structure. The enhancement of effective was also studied. Furthermore, corrections for lowest -polariton state spectra have been presented. An observable proposed dete...

The concept of local polaritons is used to describe the optical properties of mixed crystals in the frequency region of their restrahlen band. It is shown that this concept allows for a physically transparent explanation of the presence of weak features in the spectra of so-called one-mode crystals and for one-two mode behavior. The previous models were able to explain these features only with ...
