英文摘要: This project will discuss the propagation properties of gap solitons in dissipative system, mainly discuss the formation, evolution and propagation properties of nonlocal solitons and dark solitons in PT symmetric optical lattices. The research of this project includes the following contents: 1) the existence and the stability analysis of nonlocal gap solitons in PT symmetric optical lattices; 2) optical solitons in PT symmetric lattices with competing nonlocal nonlinearity, investigating the role of the competing nonlinear effect on the existence and stability of PT solitons; 3) dark solitons in PT symmetric optical lattices, including the propagation of nonlocal dark solitons and defect dark solitons in PT symmetric optical lattices. And reveal the influence of nonlocal characteristics on PT solitons and the unique role of PT symmetric optical lattices on the formation of the dark solitons..This topic is an international research focus in the field of nonlinear optics, and the study will enrich the achievements of nonlocal PT solitons and gap dark solitons, fill in the current research in this field, and will have broad prospect of research and important application value.
