Nematic liquid crystals (NLCs) are anisotropic material intermediate that combines the fluidity of liquids with the orientational order of solids. NLCs are best known for their applications in the thr...
Researchers from Cornell’s School of Applied and Engineering Physics and Samsung’s Advanced Institute of Technology have created a first-of-its-kind metalens – a metamaterial lens – that can be focuse...
When Lisa Tran set out to investigate patterns in liquid crystals, she didn’t know what to expect. When she first looked through the microscope, she saw dancing iridescent spheres with fingerprint-lik...
In previous papers, University of Pennsylvania physicists investigated the “coffee ring effect,” the ring-shaped stain of particles left after drops of coffee evaporate. In one paper, they learned how...
Liquid crystals are remarkable materials that combine the optical properties of crystalline solids with the flow properties of liquids, characteristics that come together to enable the displays found ...
Recent studies of azo-dye doped liquid crystal elastomers show a strong photomechanical response.We report on models that predict experimental results that suggest photothermal heating is the dominant...
Abstract: We investigated nonlinear absorption and photobleaching processes in a liquid crystal elastomer (LCE) doped with light-sensitive azobenzene moiety. A conventional one-dimensional holographic...
Abstract: We predict that a liquid crystal/silver nanoparticles mixture can be designed so that, in a frequency range, its effective ordinary and extraordinary permittivities have real parts of differ...
The research herein studies the Langevin dynamics allowing for an exchange of energy between liquid crystals and the thermal environment. This dynamics leads to fluctuation and dissipation behaviors...
This mini-review discusses the recent contribution of theoretical and computational physics as well as experimental efforts to the understanding of the behavior of colloidal particles in confined geom...
An international team lead by scientists at the U.S. Department of Energy’s (DOE) Center for Emergent Superconductivity, an Energy Frontier Research Center headquartered at DOE’s Brookhaven National L...
A novel series of double hydrogen bonded liquid crystals have been isolated. Hydrogen bond was formed between non mesogen chiral ingredient levo tartaric acid (LTA) and mesogenic undecyloxy benzoic ac...
We study experimentally the propagation dynamics and interaction of a pair of mutually incoherent nematicons: spatial optical solitons in nematic liquid crystals. In contrast to earlier studies, we co...
In the paper, a method to calculate the time evolution turbulence wavefronts based on the covariance method is theoretically presented in detail. According to it, the time-evolution wavefronts disturb...
