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…
Adding Binary Numbers with Discrete Solitons in Waveguide Arrays
Alaa Shaheen, Amaria Javed, U. Al Khawaja
We present a design and protocol to add binary numbers using discrete solitons in waveguide arrays. We show that the nonlinear interaction between discrete solitons in waveguide ar…
Amplifying Optical Signals with Discrete Solitons in Waveguide Arrays
Amaria Javed, Alaa Shaheen, U. Al Khawaja
We present a design and protocol to achieve an essential feature of an optical transistor, namely the amplification of input signal with the use of discrete solitons in waveguide a…
Unidirectional flow of composite bright-bright solitons through asymmetric double potential barriers and wells
Amaria Javed, T. Uthayakumar, M. O. D. Alotaibi +3
We investigate the dynamics of two component bright-bright (BB) solitons through reflectionless double barrier and double well potentials in the framework of a Manakov system gover…
