Geometric Phase in Twisted Topological Complementary Pair
Advanced Science, 2023 AbstractGeometric phase enabled by spin‐orbit coupling has attracted enormous interest in optics over the past few decades. However, it is only applicable to circularly‐polarized light and encounters substantial challenges when applied to wave fields lacking the intrinsic spin degree of freedom. Here, a new paradigm is presented for achieving geometric

κ-Deformed Phase Space, Hopf Algebroid and Twisting [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2014 Hopf algebroid structures on the Weyl algebra (phase space) are presented. We define the coproduct for the Weyl generators from Leibniz rule. The codomain of the coproduct is modified in order to obtain an algebra structure. We use the dual base to construct the target map and antipode.

Poling-free spinning process of manufacturing piezoelectric yarns for textile applications
Materials & Design, 2019 This report describes a new twist-spinning process for the manufacture of piezoelectric yarn without the need for additional poling processes. Poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) nanofibers were first electrospun and organized into a ...

Writhe in the Stretch-Twist-Fold Dynamo [PDF]
, 2009 This article looks at the influence of writhe in the stretch-twist-fold dynamo. We consider a thin flux tube distorted by simple stretch, twist, and fold motions and calculate the helicity and energy spectra. The writhe number assists in the calculations,

Crystals, 2020 Nematic twist-bend phases (NTB) are new types of nematic liquid crystalline phases with attractive properties for future electro-optic applications. However, most of these states are monotropic or are stable only in a narrow high temperature range.

Optical twists in phase and amplitude
Optics Express, 2011 Light beams with helical phase profile correspond to photons having orbital angular momentum (OAM). A Laguerre-Gaussian (LG) beam is an example where its helical phase sets a phase-singularity at the optical axis and forms a ring-shaped transverse amplitude profile.

Twist Elasticity and Anchoring in a Lamellar Nematic Phase [PDF]
Physical Review Letters, 2004 Electro-optic measurements were performed on a lamellar nematic phase in which the mesogenic moieties lie in lamellae that are separated by partially perfluorinated side groups. The twist elastic constant K22, viscosity gamma(1), and the quadratic and quartic anchoring strength coefficients are reported.
