We theoretically investigate the effect of the local variation of the crystal lattice temperature on the dynamics of breathers and rogue waves polariton solitons in exciton–polariton system. We model the condensate dynamics using the open-dissipative Gross–Pitaevskii equation for the polariton field, taking into account the local variation of the crystal lattice temperature, the time-varying cubic nonlinear dispersion effect and external potential, coupled to the rate equation of the excitonic reservoir density. With the help of the direct ansatz method and similarity transformation technique, our results reveal the existence of a strong nonlinear interaction between the local variation of the crystal lattice temperature and the polariton–polariton interaction strength due to the influence of the external pomp. We have also demonstrated that polariton rogue waves obtained are unstable because of the aperiodic exchange of energy and polaritons formed with the background.
