Anatomy of a Discovery: The Twist–Bend Nematic Phase [PDF]
Crystals, 2022 New fluid states of matter, now known as liquid crystals, were discovered at the end of the 19th century and still provide strong themes in scientific research. The applications of liquid crystals continue to attract attention, and the most successful so

Crystals, 2022 The twist–bend nematic (NTB) phase is a liquid crystal (LC) phase with a heliconical structure that typically forms below the temperature of the conventional nematic (N) phase. By contrast, the direct transition between the NTB and isotropic (Iso) phases

Induced smectic phase in binary mixtures of twist-bend nematogens
Beilstein Journal of Nanotechnology, 2018 The investigation of liquid crystal (LC) mixtures is of great interest in tailoring material properties for specific applications. The recent discovery of the twist-bend nematic phase (NTB) has sparked great interest in the scientific community, not only

Progress on Studies of Beams Carrying Twist
Photonics, 2021 Optical twist has always been a hot spot in optics since it was discovered in 1993. Twisted beams can be generated by introducing the twist phase into partially coherent beams, or by introducing the twisting phase into anisotropic beams, whose spectral ...

Template Effect of Multi-Phase Liquid Crystals
Crystals, 2021 The template effects on stability of twist structure liquid crystals (LCs) were investigated. By refilling a cholesteric LC (CLC) of different pitch into a blue phase LC (BPLC) template or a sphere phase LC (SPLC) template, a multi-phase and multi-pitch ...

Nanophotonics, 2021 Twist phase is a nontrivial second-order phase that only exists in a partially coherent beam. Such twist phase endows the partially coherent beam with orbital angular momentum (OAM) and has unique applications such as in super-resolution imaging. However,

Propagation Properties of a Twisted Hermite-Gaussian Correlated Schell-Model Beam in Free Space
Frontiers in Physics, 2022 We introduce a novel type of twisted partially coherent beams with a nonconventional correlation function, named the twisted Hermite-Gaussian correlated Schell-model (THGCSM) beam.
