Optical Control and Manipulation of Topological Defects of Liquid Crystals

We study mesoscale self-assembly of foreign microparticles in liquid crystals. The elasticity of distortions associated with the topological defect of the liquid crystal determines the interactions between the embedded microparticles. It gives rise to long-range anisotropic forces that have no analogues in regular colloidal systems dispersed in an isotropic fluid. In addition, there is a short-range structural repulsive force, and the delicate balance between them governs the positional and orientational ordering of the microparticles in liquid crystals. These forces are exploited to self-assemble the microparticles, which are further guided by laser tweezers to design advanced optical materials with complex architecture, which are likely to be useful in photonics, sensors and tunable materials. We also study "topological active matter" in which the microparticles exhibit rotational and translational motion by transducing the energy of an applied homogeneous ac electric or magnetic fields. This new class of materials, in which topological defects and elasticity of nematics play a crucial role in there dynamic structure as well as assembly and energy conversion, have enormous potential for new directions in non-equilibrium physics

Rheology of Complex Fluids

Topological defects are important in determining properties of physical systems, and are known varyingly depending on the broken symmetry. In the early Universe, they are called cosmic strings; in superfluid helium, they are vortices; in periodic crystals, one refers to dislocations. These defects are crucial for determining the physical properties of the materials. We study the rheological properties of exotic liquid crystals in which the topological defects are inherent to the structures. We also study the active and passive rheology of liquid crystals, polymers, gels and various other soft materials.

Soft Matter Photonics

Liquid crystals based optical micro-resonators for Whispering Gallery Mode (WGM) resonance and lasing, Self-assembled structures of droplets, colloidal particles.

Active Matter

Microparticles with topological defects in uniaxial nematic liquid crystals exhibit rotational and translational motion by transducing external energy. We study this new class of materials, in which topological defects and elasticity of nematics play a crucial role in the dynamic structure as well as assembly and energy conversion. We also study the collective and dynamic behavior of living microorganisms like millipedes, bacteria algae etc.

Structures and Properties of Unconventional Liquid Crystals The phase transitions, physical properties and the electro-optical responses in unconventional liquid crystals are drastically different from those of conventional liquid crystals. We study phase transitions and viscoelastic properties of unconventional liquid crystals.
