Dark solitons, breathers, rogue waves, and their dynamic behaviors in the nonlocal nonlinear Schrödinger equation
摘要
This study investigates dark solitons, breathers, and rogue waves of the nonlocal nonlinear Schrödinger (NNLS) equation, utilizing the bilinear Kadomtsev–Petviashvili hierarchy reduction method. For the focusing NNLS equation, it is shown that both breathers and rogue waves exist, whereas for the defocusing NNLS equation, only dark solitons and breathers are present. Due to the inherent parity-time symmetry, these solutions always appear in pairs, with no degeneracy. As an application, the dynamic behaviors of these solitary wave solutions are systematically analyzed and illustrated through representative figures.
