Generating the Hopf fibration experimentally in nematic liquid crystals.
نویسندگان
چکیده
The Hopf fibration is an example of a texture: a topologically stable, smooth, global configuration of a field. Here we demonstrate the controlled sculpting of the Hopf fibration in nematic liquid crystals through the control of point defects. We demonstrate how these are related to torons by use of a topological visualization technique derived from the Pontryagin-Thom construction.

Investigation into the temperature dependence of isotropic- nematic phase transition of Gay- Berne liquid crystals
Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...
متن کاملOrigin of traveling rolls in electroconvection of nematic liquid crystals.
Electroconvection in nematic liquid crystals exhibits a Hopf bifurcation to traveling rolls for a wide parameter range. The model normally used to describe electroconvection fails to predict this. A recent theoretical extension, the weak-electrolyte model, incorporates the dissociation-recombination reaction of the ionic dopant in the sample and does predict a Hopf bifurcation for a range of pa...
متن کاملKnotted defects in nematic liquid crystals.
We show that the number of distinct topological states associated with a given knotted defect, L, in a nematic liquid crystal is equal to the determinant of the link L. We give an interpretation of these states, demonstrate how they may be identified in experiments, and describe the consequences for material behavior and interactions between multiple knots. We show that stable knots can be crea...

متن کاملTopology with Liquid Crystals
With lasers or electron beams, it is now possible to mold a variety of soft and hard materials into different shapes with new properties and functionalities. These techniques also provide some of the few ways to generate topological shapes from mathematics, like knots and vortices, in a real-world system. In Physical Review Letters, Bryan Gin-ge Chen of the University of Pennsylvania (now at Le...
