• Two-dimensional phases of confined 5-cyano-biphenyl: Computer simulation study
  Author(s): Violetta Raczyńska, Krzysztof Górny, Przemysław Raczyński, Zbigniew Dendzik, and Szymon StarzonekThe properties of composites of mesogens and two-dimensional (2D) materials are of great interest due to their practical applications in flexible displays, optoelectronics, microelectronics, and novel nanodevices. The properties of such composites are […]
• Effect of CdSe/ZnS quantum dot dispersion on phase transitional behavior of 8OCB liquid crystal
  Author(s): Aysha Rani, Susanta Chakraborty, and Aloka SinhaWe report the effect on the phase transitional behavior of 8OCB liquid crystal (LC) doped with functionalized CdSe/ZnS quantum dots (QDs) in different concentrations. The temperature-dependent data of high-resolution optical birefringence and dielectric anisotropy are utilized to characterize the cr… […]
• Pair interaction of localized topological structures in confined chiral media
  Author(s): I. M. Tambovtsev, I. S. Lobanov, Alexei D. Kiselev, and V. M. UzdinWe study pairwise interactions between localized topological structures in chiral magnetic and cholesteric liquid crystal (CLC) systems confined in the planar geometry. Our calculations for magnetics are based on the lattice model that takes into account the bulk and surface anisot […]
• Magnetic-field-driven director configuration transitions in radial nematic liquid crystal droplets
  Author(s): Sophie Ettinger, Charlotte G. Slaughter, Sebastian Hurtado Parra, James M. Kikkawa, Peter J. Collings, and A. G. YodhWe study the director configurations of nematic liquid crystal (NLC) droplets with homeotropic anchoring in a magnetic field and report observation of a magnetic-field-driven transition from a deformed radial to an axial-with-defect […]
• Dirac points, new photonic band gaps, and effect of magnetically induced transparency in dichroic cholesteric liquid crystals with wavelength-dependent magneto-optical activity parameter
  Author(s): A. H. GevorgyanWe investigated the properties of cholesteric liquid crystals (CLCs) being in an external static magnetic field directed along the helix axis. We considered a dichroic CLC, that is, CLC with parameters $\mathrm{Re}\mathrm{Δ}=\frac{\mathrm{Re}{ɛ}_{1}−\mathrm{Re}{ɛ}_{2}}{2}=0$ and $\mathrm{Im}\mathrm{…[Phys. Rev. E 108, 024703] Publis […]
• Proton-decoupled deuterium NMR study of an asymmetric liquid crystal dimer having two nematic phases
  Author(s): C. Chamignon, M. Lelli, J. W. Emsley, G. R. Luckhurst, and H. ZimmermannProton-decoupled deuterium NMR spectra were obtained for an asymmetric liquid crystal dimer 1-(4-cyanobiphenyl-4′-yloxy)-6-(4-cyanobiphenyl-4′-yl)hexane (CB6OCB) containing a single -${\mathrm{CD}}_{2}$- group. The sample has two nematic liquid crystal phases: a twist-bend nem […]
• Symbiotic dynamics in living liquid crystals
  Author(s): Aditya Vats, Pradeep Kumar Yadav, Varsha Banerjee, and Sanjay PuriAn amalgam of nematic liquid crystals and active matter, referred to as living liquid crystals, is a promising self-healing material with futuristic applications for targeted delivery of information and microcargo. We provide a phenomenological model to study the symbiotic pattern d […]
• Stability conditions of a twist-bend nematic phase according to Barbero's theory
  Author(s): Michał SzmigielskiThe stability conditions of twist-bend nematics given by Barbero et al. [Phys. Rev. E 92, 030501(R) (2015)] lead to doubtful conclusions when the influence of the magnetic field on the ${N}_{\mathrm{TB}}$ structure is analyzed. For this reason, the stability criteria have been redetermined in the pr…[Phys. Rev. E 108, 014701] Pub […]
• Thin pyramidal cones in nematic liquid crystals
  Author(s): Seyed Reza Seyednejad, Saeedeh Shoarinejad, Mohammad Reza Mozaffari, and Faezeh Amini JoneghaniThe present study investigates the arrangement of hollow pyramidal cone shells and their interactions with degenerate planar anchoring on the inner and outer surfaces of particles within the nematic host. The shell thickness is in order of the nematic co […]
• What promotes smectic order: Applying mean-field theory to the ends
  Author(s): David A. King and Randall D. KamienNot every particle that forms a nematic liquid crystal makes a smectic. The particle tip is critical for this behavior. Ellipsoids do not make a smectic, but spherocylinders do. Similarly, only those $N$-CB alkylcyanobiphenyls with sufficiently long ($N≥8$ carbons) alkane tails form smectics. We und…[Phys. Rev. E […]
