摘要

We study the interaction of discrete (narrow) dark solitons with point defects in the integrable Ablowitz-Ladik lattice model. On-site and inter-site (bond) defects are considered. The stability of the analytical solutions for solitons bound to the defect is investigated. A comparison with the standard discrete nonlinear Schrodinger equation is made. Scattering of the dark solitons from point defects of different types is studied numerically. The model plays an important role in numerous physical systems, especially when the corresponding elementary excitations obey Pauli statistics.
