While in linear lattices only one localized mode of this type mayKeywords: Existence and stability; Linear lattices; Localized modes; Localized state; Non-Linearity; Nonlinear localized modes; Nonlinear mode; Phase slips; Photonic lattice; Rectangular symmetry; Surface modes; Symmetric state; Waveguide channels; Photonics; Waveg200910.1103/PhysRevA.80.0638122016-02-24
