Special Issue Information

Dear Colleagues,

The nonlinear Schrödinger equation (NLSE) is involved in various physical settings. It is a partial differential equation that governs the wave function of a quantum-mechanical system. It is known that NLSE can be solved exactly only for the simplest of systems. Rapid computational methods bring the promise of solving the NLSE for complex systems and have opened extraordinary theoretic and application-based opportunities. In recent years, abundant theories and algorithms have been developed and proposed and applied to solve NLSE practice problems. Motivated by these discoveries, substantial techniques of solving NLSE are investigated in various domains, such as surface gravity waves, superconductivity, nonlinear optics, and BEC, etc.

This Special Issue “Symmetry in Nonlinear Schrödinger Equations” aims to gather and showcase the most recent advances in the nonlinear Schrödinger equation (NLSE). We are interested in the whole spectrum of nonlinear Schrödinger equations (NLSEs) and their symmetries applied to relevant problems from all related areas, including numerical simulation and modeling, numerical algorithm, theoretical analysis and applications in practical problems. A list of the topics of interest can be found below:

  • Theoretical analysis of NLSEs;
  • The symmetry in NLSEs;
  • Various codes for solving 1D/2D/3D NLSEs;
  • Numerical algorithms for solving NLSEs;
  • Multi-body NLSEs;
  • Application of NLSEs in a wide range of areas

Abstract
In this paper, we use the multilinear variable separation approach involving two arbitrary variable separation functions to construct a new variable separation solution of the (4+1)-dimensional Boiti–Leon–Manna–Pempinelli equation. Through considering different parameters, three types of local excitations including dromions, lumps, and ring solitons [...] Read more.
In this paper, we use the multilinear variable separation approach involving two arbitrary variable separation functions to construct a new variable separation solution of the (4+1)-dimensional Boiti–Leon–Manna–Pempinelli equation. Through considering different parameters, three types of local excitations including dromions, lumps, and ring solitons are constructed. Dromion molecules, lump molecules, ring soliton molecules, and their interactions are analyzed through the velocity resonance mechanism. In addition, the results reveal the elastic and inelastic interactions between solitons. We discuss some dynamical properties of these solitons and soliton molecules obtained analytically. Three-dimensional diagrams and contour plots of the solution are given to help understand the physical mechanism of the solutions. Full article
