SmC ~* 液体的光铁电响应理论

Theory of photoferroelectric response in SmC* liquids

Milos Knezevic, Mark Warner

摘要:

我们关注的是SmC* 液体的液晶性和极性顺序的照明修改。特别是,我们表明,由于吸收和动态的不均匀性,可以是复杂的。当被照射时,偏振随温度的变化从假设均匀性的变化进行了修改。由于非均匀性,偏振随照明的表观变化将被低估。的动力学取决于光转换穿透样品的传播战线。

英文摘要:

We are concerned with the modification of liquid crystalline and polar order in SmC* liquids by illumination. In particular we show that non-uniformity due to absorption and also dynamics, can be complex. The variation of polarization with temperature, while illuminated, is modified from that assuming uniformity. Apparent changes of polarization with illumination will be shown to be underestimated due to non-uniformity. The dynamics is shown to depend on propagating fronts of photo-conversion penetrating the sample.
