Abstract:
We demonstrate spatial soliton interaction and rotation in optically induced Bessel-like photonic lattices. Particlelike circular motion as well as planetlike orbiting of two solitons is observed under different initial excitations in the ring-shaped lattices. We show that, while small rotation/oscillation of solitons can be initiated by soliton self-bending, planetlike orbiting of a "satellite" soliton can be realized by imposing an initial angular momentum from a vortex beam. Our experimental results are corroborated by numerical simulations.

When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states that no two...
