Significance Topological defects play a defining role in systems as extensive as the universe and as minuscule as a microbial colony. Despite significant advances in our understanding of topological defects and their mutual interactions, little is known about the formation and dynamics of defects across different material fields embedded within the same system. Here, using nematic microfluidics as a test bed, we report how topological defects in the flow and the orientational fields emerge and…

Structures and topological defects in pressure-driven lyotropic chromonic liquid crystals
TLDR
A single-shot quantitative polarization imaging method is employed, termed polarized shearing interference microscopy, to quantify the spatial distribution and the dynamics of the structures emerging in nematic disodium cromoglycate solutions in a microfluidic channel, and shows that pure-twist disclination loops nucleate in the bulk flow over a range of shear rates.
Active microfluidic transport in two-dimensional handlebodies.
TLDR
It is shown that confining a tubulin-kinesin active nematic to a network of connected annular microfluidic channels enables controlled directional flows and autonomous transport.
Microfluidic control over topological states in channel-confined nematic flows
TLDR
It is shown how precise tuning of the driving pressure can be used to stabilize and manipulate a previously unresearched topologically protected chiral intermediate state which arises before the homeotropic to flow-aligned transition.

Field generated nematic microflows via backflow mechanism
TLDR
This article demonstrates the contact-free generation of microfluidic material flows in nematic fluids by external electric and optical fields based on the dynamic backflow coupling between nematic order and material flow and shows that a laser beam with rotating linear polarization can create a vortex-like flow structure and can act as a local flow pump without moving mechanical parts.

Mutually tangled colloidal knots and induced defect loops in nematic fields.
TLDR
It is demonstrated that bulk and surface defects in nematic fluids can be patterned by tuning the topology of colloidal particles dispersed in them by taking advantage of two-photon photopolymerization techniques to make knot-shaped microparticles.

The results reveal that topological defects in LCs are a versatile class of three-dimensional, dynamic and reconfigurable templates that can direct processes of molecular self-assembly.
Anisotropy in the annihilation dynamics of umbilic defects in nematic liquid crystals.
TLDR
The defects' speed is interpreted in terms of their overlap and the speed asymmetry as arising from backflow effects and anisotropy in the elastic constants, which is found to be essentially constant for varying external conditions which do not change the material properties of the liquid crystal material.
