Biaxial order parameter in the homologous series of orthogonal bent-core smectic liquid crystals
Vij, Jagdish; Panarin, Yuri (2013)The fundamental parameter of the uniaxial liquid crystalline state that governs nearly all of its physical properties is the primary orientational order parameter (S) for the long axes of molecules with respect to the ... -
Electrooptic, pyroelectric, dielectric spectroscopic studies of nematic and twist-bend nematic phases of achiral hockey-shaped bent-core liquid crystal
Vij, Jagdish; Panarin, Yuri; Yadav, Neelam (2022)Experimental and theoretical investigations of the twist-bend nematic (NTB) phase in liquid crystals have recently received significant attention for reasons of unusual and interesting characteristics of the NTB. Though ... -
Flexoelectric polarization studies in bent-core nematic liquid crystals
Vij, Jagdish; Panarin, Yuri (2015)The flexoelectric polarization ( P f ) of four bent-core nematic liquid crystals (LCs) has been measured using the pyroelectric effect. Hybrid aligned nematic cells are fabricated for measuring the pyroelectric response ... -
Formation and development of nanometer-sized cybotactic clusters in bent-core nematic liquid crystalline compounds
Vij, Jagdish; Panarin, Yuri (2018)Two homologue achiral bent-core liquid crystals (LCs), BCN66 and BCN84, in their nematic phases are studied by dielectric spectroscopy in the frequency range 10 Hz–10 MHz. In each of these compounds, two relaxation processes ... -
Liquid crystal display modes in a nontilted bent-core biaxial smectic liquid crystal
Vij, Jagdish; Panarin, Yuri (2010)Liquid crystal display (LCD) modes associated with the rotation of the secondary director in nontilted, biaxial smectic phase of an achiral bent-core compound are demonstrated. For LCDs, we find that at least four display ... -
Sequence of Four Orthogonal Smectic Phases in an Achiral Bent-Core Liquid Crystal: Evidence for the SmAP(alpha) Phase
Vij, Jagdish; Panarin, Yuri (2011)The mesomorphic properties of an achiral bent-core liquid crystal derived from 4-cyanoresorcinol are studied by polarizing optical microscopy, x-ray diffraction, and second harmonic electro-optic response. It shows a novel ... -
Spontaneous helix formation in non-chiral bent-core liquid crystals with fast linear electro-optic effect
Vij, Jagdish; Panov, Vitaly; Panarin, Yuri (2016)Liquid crystals (LCs) represent one of the foundations of modern communication and photonic technologies. Present display technologies are based mainly on nematic LCs, which suffer from limited response time for use in ...
