nematic liquid crystals中的矢量涡旋孤子

Vector vortex solitons in nematic liquid crystals

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

摘要:

分析了双折射液晶中双分量矢量孤子的存在性和稳定性,其中一个分量带有角动量,描述了涡旋光束。我们表明,非局部,非线性响应可以显着增强场耦合,导致稳定的涡旋光束时,第二光束的振幅超过一定的阈值。我们开发了一个变分的方法来描述这种效果分析。

英文摘要:

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.
