Evolution of superposition solitons and breathers in strongly nonlocal nonlinear media

Abstract We analyzed and obtained the condition to form a new kind of two-dimensional solitons with complex structure named as “superposition solitons and breathers” in strongly nonlocal media based on the analytical and numerical investigations. Furthermore we investigated how such solitons and breathers persist and are robust when degree of nonlocality is gradually decreased when taken the fully nonlinear system, then we can find such solitons by using the method.
