Dissipative surface solitons in two-dimensional truncated lattices with linear gain and loss
Changming Huang, Yan Wang, Pengcheng Liu +2
Dissipative solitons constitute a robust class of self-localized nonlinear states sustained by the dynamic balance between nonlinearity and gain-loss, possessing an intrinsic stabi…
