Webthe nematic order parameter on the coverage. For this purpose, a free-energy-minimization approach can be applied.9 The procedure is as follows: (i) We choose δ y = 0 and δ x ≠ 0, this leaves N 2 and N 3 in an isotropic state, see eq 15. We can do this without losing any generality, since a pure nematic state is given by WebWe study a class of models for bent-core molecules using low density version of Local Density Functional Theory. Arms of the molecules are modeled using two- and three Gay-Berne (GB) interacting units of uniaxial and b…

WebA novel liquid crystal integrated modulation-depth-adjustable in-fiber modulator is proposed. The liquid crystal is encapsulated in a specially designed capillary optical fiber with tubular structure. The experimental results show that the liquid crystal under the electric field can influence the light intensity in the tubular core of the fiber. The light at 632.8 nm in the … WebNematic shells are effec-tively two-dimensional (2D) systems, with the ⃗ orientations confined within a curved 2D film (Nelson, 2002), which generally results in the domination of topological defects (TDs) in such structures. Topological defects (TDs) in 2D nematic films are identified by their winding number ,
