Quantum pseudodots under the influence of external vector and scalar fields
《Chinese Physics B》2018年第8期109-117,共9页M Eshghi S M Ikhdairt 
We study the spherical quantum pseudodots in the Schr6dinger equation by using the pseudo-harmonic plus harmonic oscillator potentials considering the effect of the external electric and magnetic fields. The finite en...

Solving unsteady Schr?dinger equation using the improved element-free Galerkin method被引量：3
《Chinese Physics B》2016年第2期35-43,共9页程荣军 程玉民 
Project supported by the National Natural Science Foundation of China(Grant No.11171208);the Natural Science Foundation of Zhejiang Province,China(Grant No.LY15A020007);the Natural Science Foundation of Ningbo City(Grant No.2014A610028);the K.C.Wong Magna Fund in Ningbo University,China
By employing the improved moving least-square （IMLS） approximation, the improved element-free Galerkin （IEFG） method is presented for the unsteady Schrodinger equation. In the IEFG method, the two-dimensional （2D...

Multi-symplectic variational integrators for nonlinear Schrdinger equations with variable coefficients
《Chinese Physics B》2016年第1期419-427,共9页廖翠萃 崔金超 梁久祯 丁效华 
supported by the National Natural Science Foundation of China(Grant No.11401259);the Fundamental Research Funds for the Central Universities,China(Grant No.JUSRR11407)
In this paper, we propose a variational integrator for nonlinear Schrodinger equations with variable coefficients. It is shown that our variational integrator is naturally multi-symplectic. The discrete multi-symplect...

Multi-symplectic method for the coupled Schrdinger–KdV equations
《Chinese Physics B》2014年第8期226-232,共7页张弘 宋松和 周炜恩 陈绪栋 
Project supported by the National Natural Science Foundation of China(Grant No.91130013);the Open Foundation of State Key Laboratory of High Performance Computing
In this paper, we present a multi-symplectic Hamiltonian formulation of the coupled Schrtidinger-KdV equations （CS＇KE） with periodic boundary conditions. Then we develop a novel multi-symplectic Fourier pseudospect...

Chaos control in the nonlinear Schrdinger equation with Kerr law nonlinearity
《Chinese Physics B》2014年第2期44-48,共5页殷久利 赵刘威 田立新 
Project supported by the National Natural Science Foundation of China (Grant No.11101191)
The nonlinear Schr6dinger equation with Kerr law nonlinearity in the two-frequency interference is studied by the numerical method. Chaos occurs easily due to the absence of damping. This phenomenon will cause the dis...

Solving coupled nonlinear Schrodinger equations via a direct discontinuous Galerkin method
《Chinese Physics B》2012年第3期10-14,共5页
Project supported by the National Natural Science Foundation of China （Grant No 11171038）.
In this work, we present the direct discontinuous Galerkin （DDG） method for the one-dimensional coupled nonlinear Schr5dinger （CNLS） equation. We prove that the new discontinuous Galerkin method preserves the disc...
