Influence of nonlocality on the polarization dynamics of an electric field pulse in a medium with cubic nonlinearity is under study. Nonlinear equations are solved using a variational approach. It is shown that nonlocal and chiral effects cause trajectory oscillations and nonlinear polarization rotation of soliton pulses of the field.

介质响应非定域性对孤子极化的影响

非局域性对立方非线性介质中电场脉冲极化动力学的影响正在研究中。非线性方程使用变分方法求解。结果表明，非局域和手性效应会导致场的孤子脉冲的轨迹振荡和非线性偏振旋转。
