Upper threshold for stability of multipole-mode solitons in nonlocal nonlinear media

Zhiyong Xu; Yaroslav V. Kartashov; Lluis Torner


We address the stability of multipole-mode solitons in nonlocal Kerr-type nonlinear media. Such solitons comprise several out-of-phase peaks packed together by the forces acting between them. We discover that dipole-, triple-, and quadrupole-mode solitons can be made stable, whereas all higher-order soliton bound states are unstable.
