Oblique solitons generated by the flow of a polariton condensate past an obstacle
- Russian Academy of Sciences, Institute for Spectroscopy (Russian Federation)
The formation of oblique solitons in a polariton condensate flowing past an obstacle is considered. Because of the finite lifetime of polaritons, the condensate flow is inhomogeneous, which leads to a significant modification of the conditions necessary for the generation of oblique solitons as compared to the conditions established earlier for the flow of an atomic condensate. In particular, it is established that oblique solitons in the polariton case can be generated by a subsonic flow of the condensate in agreement with the results of recent experiments [9]. The geometric shape and other parameters of oblique solitons are analytically calculated using a model based on the nonlinear Schroedinger equation with damping, and the analytical results are confirmed by numerical simulations.
