Families of Skyrmions in Two-Dimensional Spin-1/2 Systems
Amaria Javed, L. Al Sakkaf, U. Al Khawaja
We find Skyrmion-like topological excitations for a two-dimensional spin-1/2 system. Expressing the spinor wavefunction in terms of a rotation operator maps the spin-1/2 system to…
High-speed soliton ejection generated from the scattering of bright solitons by modulated reflectionless potential wells
T. Uthayakumar, L. Al Sakkaf, U. Al Khawaja
We investigate numerically and theoretically the conditions leading to soliton ejection stimulated through the scattering of bright solitons by modulated reflectionless potential w…
Singular Soliton Molecules of the Nonlinear Schrodinger Equation
Khelifa Mohammed Elhadj, L. Al Sakkaf, U. Al Khawaja +1
We derive an exact solution to the local nonlinear Schrödinger equation (NLSE) using the Darboux transformation method. The new solution describes the profile and dynamics of a two…
