Correlation properties of bose systems of polariton type

The nonequilibrium quantum correlation and fluctuation properties of a two-mode Bose system with effective Hamiltonian of polariton type are investigated. The exact evolution of the operators is found by a Bogolyubov canonical transformation. The possibility of periodic variation of the statistical properties of such a system is demonstrated, and also the occurrence of a squeezed state of a field initially in a random state. Investigation of the cross correlation function demonstrates the possibility of exchange of statistical properties between interacting fields.
