Profile Summary

• Photorefractive effect in liquid crystals. Theoretical modelling of photorefractive effect and two beam coupling in LC filled with ferroelectric nanoparticles, LC placed between two photo-conducting surfaces. Gain coefficient is calculated and compared with the experimental results
• LC filled with nano-and micro-particles. Estimated the phase transition temperature shift and order parameter change due to the particles presence. Electro- magneto-optics of LC filled with ferroic particles. Threshold electric/magnetic field and refractive index dependence on the field strength are calculated and compared with the experimental data
• Adaptive LC lenses. Focal length dependence on the applied electric field is calculated
• Polymer dispersed liquid crystals (PDLC). Effective dielectric function and light scattering cross sections are calculated in PDLC
• Photoalignment of LCs. Theoretical modelling of photo-induced change in liquid crystal director anchoring and pretilt angle onto photosensitive aligning surfaces
• Surface phenomena and anchoring effects in liquid crystals. Theoretical modelling of director finite anchoring effect onto light scattering in LCs
• Linear and nonlinear optics of liquid crystals (including conformational nonlinearity) Theoretical modelling of LC refractive index change and phase transition temperature shift due to photoinduced change in the conformation of LC molecules
