Bound states of spatial optical dark solitons in nonlocal media

doi:10.1088/1674-1056/21/4/040505

Abstract It is shown that multiple dark solitons can form bound states in a series of balance distances in nonlocal bulk media. Dark solitons can either attract or repel each other depending on their separated distance. The stability of such bound states are studied numerically. There exist unstable degenerate bound states decaying in different ways and having different lifetimes.

Keywords: nonlocal nonlinear Schr?dinger equation dark soliton bound state
