摘要：

We study gray solitons in nonlocal nonlinear media and show that they are stable and can form bound states. We reveal that the gray soliton velocity depends on the nonlocality degree and that it can be drastically reduced in highly nonlocal media. This is in contrast with the case of local media, where the maximal velocity is dictated solely by the asymptotic soliton amplitude. (c) 2007 Optical Society of America.
