Vector vortex solitons in nematic liquid crystals

Xu, Zhiyong; Smyth, Noel F.; Minzoni, Antonmaria A.; Kivshar, Yuri S.

Description

We analyze the existence and stability of two-component vector solitons in nematic liquid crystals for which one of the components carries angular momentum and describes a vortex beam. We demonstrate that the nonlocal, nonlinear response can dramatically enhance the field coupling leading to the stabilization of the vortex beam when the amplitude of the second beam exceeds some threshold value. We develop a variational approach to describe this effect analytically.
