| Abstract | By adopting a mean-field Gross-Pitaevskii description of spinor polariton Bose-Einstein condensates under nonresonant pumping, we investigate the static and dynamical properties of dark-bright (DB) solitons. We derive the equation of motion for the center of mass of the DB solitons' center analytically by using the Hamiltonian approach. The resulting equation captures how the combination of the open-dissipative character and the spin degrees of freedom of a polariton Bose-Einstein condensate affects the properties of DB solitons, i.e. DB solitons relax by blending with the background at a finite time. In this case, we also determine the lifetime of the DB solitons. Further numerical solutions of the modified dissipative two-component Gross- Pitaevskii equations are in excellent agreement with the analytical results. In the presence of the Langevin noise, we demonstrate that the DB solitons can still propagate for a long time, which is sufficient for their experimental observations within current facilities. |
