Query: Dark-bright solitons in spinor polariton condensates under nonresonant
  pumping   Adopting a mean-field Gross-Pitaevskii description for a spinor polariton
Bose-Einstein condensates under non-resonant pumping, we investigate the static
and dynamical properties of dark-bright solitons. We derive analytically the
equation of motion for the center of mass of the dark-bright soliton center,
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 a dark-bright
soliton, i.e. the dark-bright soliton relaxes by blending with the background
at a finite time. In this case, we also determine the life time of the DB
soliton. Further numerical solutions of the modified dissipative two-component
Gross-Pitaevskii equations are in excellent agreement with the analytical
results. In 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.
