Author(s): C. Anquetil-Deck, D. J. Cleaver, and P. I. C. TeixeiraWe have investigated, by Monte Carlo simulation, the orientational structure of very thin films of a discotic liquid crystal (DLC) confined between hybrid walls of controllable penetrability, as a function of wall separation ${L}_{z}$. Our purpose was to clarify whether, as predicted by continu […]
Author(s): Daniel Salgado-Blanco, Enrique Díaz-Herrera, José A. Martínez-González, and Carlos I. MendozaThe self-assembly of liquid crystal droplets and shells represents a captivating frontier in soft matter physics, promising precision engineering of functional materials. In this study, we delve into the phase behavior and investigate defect formation patt […]
Author(s): Lidiane Maria de Souza, Junaid Sofi, and Erms PereiraThe synthesis of ferroelectric nematic liquid crystals (FNLCs) concludes the long wait for their existence and potential usage in multiple liquid crystal based applications. In FNLCs, electric polarization in the nematic phase significantly decreases the switching time of in-on display pixels. I […]
Author(s): Joseph R. L. Cousins, Nigel J. Mottram, and Stephen K. WilsonMotivated by the variety of applications in which nematic Hele-Shaw flow occurs, a theoretical model for Hele-Shaw flow of a nematic liquid crystal is formulated and analyzed. We derive the thin-film Ericksen-Leslie equations that govern nematic Hele-Shaw flow, and consider two important […]
Author(s): Aditya Vats, Varsha Banerjee, and Sanjay PuriWe study living liquid crystals (LLCs), which are an amalgam of nematic liquid crystals (LCs) and active matter (AM). These LLCs are placed in contact with surfaces which impose planar/homeotropic boundary conditions on the director field of the LC and the polarization field of the AM. The interplay…[Ph […]
Author(s): Aitor Erkoreka and Josu Martinez-PerdigueroFerroelectric nematic liquid crystals are currently being subject to a plethora of investigations since they are of great fundamental interest and could potentially foster promising applications. However, many basic aspects are still poorly understood, among which the problem of the dielectric const…[Phys […]
Author(s): P. V. Dolganov, N. A. Spiridenko, and V. K. DolganovOrdered chain structures from topological defects of opposite charges (“necklaces” of defects) were prepared and their dynamics and cooperative rearrangement were investigated. We studied topological defects in nematic films with change of the Euler characteristic induced by temperature. Topologi […]
Author(s): E. S. Pikina, A. R. Muratov, E. I. Kats, and V. V. LebedevElectrohydrodynamic phenomena in liquid crystals constitute an old but still very active research area. The reason is that these phenomena play the key role in various applications of liquid crystals and due to the general interest of the physical community in out-of-equilibrium systems. Ne […]
Author(s): Josep Salud, Nerea Sebastián, María R. de la Fuente, S. Diez-Berart, and David O. LópezA comprehensive dynamic analysis of the dielectric relaxation-time data across a broad temperature range for both isotropic and nematic phases has been conducted on the CBO3O.Py liquid crystal dimer, the shorter chain-length compound within the highly nonsymmetr […]
Author(s): Mariana Casaroto, Cesare Chiccoli, Luiz Roberto Evangelista, Paolo Pasini, Rodolfo Teixeira de Souza, Claudio Zannoni, and Rafael Soares ZolaWe consider a nematic liquid crystal film confined to a flat cell with homeotropic and planar patterned hybrid anchoring and show, using Monte Carlo simulations, the possibility of the system to stabilize lin […]
