Abstract

Vortex solutions of coupled Gross–Pitaevskii equations for a two-component Bose–Einstein condensate of exciton polaritons have been described theoretically with the inclusion of the dependence of the Rabi splitting energy on the density of the exciton component. It has been shown that the inclusion of blueshift leads to a considerable decrease in the densities of both components of the condensate. The spatial profiles of excitons and photons in the polariton system, as well as the energy of vortex excitation formation, have been calculated taking into account nonlinear corrections.
