Transverse instability of dark solitons in spin-orbit coupled polariton condensates
Transverse instability of dark solitons in spin-orbit coupled polariton condensates
We consider dark solitons and their stability in spin-orbit coupled polariton condensates. The system supports spinor solitons of two types: conventional (symmetric) dark solitons and asymmetric half-dark solitons. They demonstrate essentially different behavior upon variation of the strength of spin-orbit coupling. One-dimensional spin-orbit coupled dark solitons are usually unstable, while …
