We investigate the attractive interaction between spatial solitons in nematic liquid crystals with a tunable nonlinearity and a constant nonlocality. The experimental study, carried out by controlling the orientation of the optic axis via the electro-optic response, shows how the interactions depend on reorientation, in excellent agreement with a model accounting for the anisotropic nature of the dielectric.
我们研究了具有可调谐非线性和恒定非局域性的向列相液晶中空问孤子之间的吸引力相互作用。通过电光响应控制光轴方向的实验研究表明了相互作用如何取决于重新取向，这与考虑介电各向异性的模型非常吻合。
