Vector NLS solitons interacting with a boundary被引量：1
《Communications in Theoretical Physics》2021年第4期45-51,共7页Cheng Zhang Da-jun Zhang 
NSFC(11601312);NSFC(11875040)。
We construct multi-soliton solutions of the n-component vector nonlinear Schrödinger equation on the half-line subject to two classes of integrable boundary conditions(BCs):the homogeneous Robin BCs and the mixed Neum...

Dark Solitons for the Defocusing Cubic Nonlinear Schr?dinger Equation with the Spatially Periodic Potential and Nonlinearity
《Communications in Theoretical Physics》2015年第9期309-319,共11页闫振亚 闫方驰 
Supported by the National Natural Science Foundation of China under Grant No.61178091;the National Key Basic Research Program of China under Grant No.2011CB302400;the Open Project Program of State Key Laboratory of Theoretical Physics,Institute of Theoretical Physics,Chinese Academy of Sciences,China under Grant No.Y4KF211CJ1
We study the existence of dark solitons of the defocusing cubic nonlinear Schr¨odinger(NLS) eqaution with the spatially-periodic potential and nonlinearity. Firstly, we propose six families of upper and lower solutio...
