Solitons in one-dimensional nonlinear Schrodinger lattices with a local inhomogeneity
Flow characteristics discrete nonlinear schrodinger equation linear point defects focusing on the lattice defects

In this paper we analyze the existence, stability, dynamical formation, and mobility properties of localized solutions in a one-dimensional system described by the discrete nonlinear Schrödinger ...
Collisional-inhomogeneity-induced generation of matter-wave dark solitons
Dark soliton condensate numerical simulation of the space is not uniform shear wave scattering length one-dimensional BEC 2 d

We propose an experimentally relevant protocol for the controlled generation of matter-wave dark solitons in atomic Bose–Einstein condensates (BECs). In particular, using direct numerical simulations,...
Adaptation to anisotropy and inhomogeneity via dyadic piecewise polynomial selection
Adaptation to anisotropy inhomogeneity via dyadic piecewise polynomial selection
