Time-resolved Diffusing Wave Spectroscopy to Enable Ultrafast Electro-optic Relaxation Dynamic in Liquid Crystals
Suman Kalyan Manna, Laurent Dupont, Guoqiang Li
Enabling control over a spontaneous dynamic process is a very complicated task in practice because of its statistical nature, and electro-optic (E-O) relaxation dynamic in a nemati…

Theoretical analysis of nanoparticle-induced homeotropic alignment in nematic liquid crystals
Amit Choudhary, Thomas F. George, Guoqiang Li
A theoretical analysis of homeotropic alignment induced by nanoparticles (NPs) in a nematic liquid crystal (NLC) sample cell is presented. It is found that such alignment on the su…
