Experimental synthesis of partially coherent beam with controllable twist phase and measuring its orbital angular momentum [PDF]

open access: yesNanophotonics, 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,

Anatomy of a Discovery: The Twist–Bend Nematic Phase [PDF]

open access: yesCrystals, 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

Induced smectic phase in binary mixtures of twist-bend nematogens

open access: yesBeilstein 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

Quantum phases in twisted homobilayer transition metal dichalcogenides. [PDF]

open access: yesNatl Sci Rev
ABSTRACT Twisted homobilayer transition metal dichalcogenides—specifically twisted bilayer MoTe$_2$ and twisted bilayer WSe$_2$—have recently emerged as a versatile platform for strongly correlated and topological phases of matter. These two-dimensional systems host tunable flat Chern bands in which Coulomb interactions can dominate ...

Progress on Studies of Beams Carrying Twist

open access: yesPhotonics, 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

open access: yesCrystals, 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 ...

Propagation Properties of a Twisted Hermite-Gaussian Correlated Schell-Model Beam in Free Space

open access: yesFrontiers 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.
