Transverse structure of the pion beyond leading twist with basis light-front quantization [PDF]

open access: yesPhysics Letters B, 2023
We investigate the twist-3 transverse-momentum-dependent parton distribution functions (TMDs) of the pion with basis light-front quantization. The twist-3 TMDs are not independent and can be decomposed into twist-2 and genuine twist-3 terms from the ...

Implicative twist-structures

open access: yesAlgebra universalis, 2014
The twist-structure construction is used to represent algebras related to non-classical logics (e.g., Nelson algebras, bilattices) as a special kind of power of better-known algebraic structures (distributive lattices, Heyting algebras). We study a specific type of twist-structure (called implicative twist-structure) obtained as a power of a ...

Twist Structures and Nelson Conuclei

open access: yesStudia Logica, 2021
Motivated by Kalman residuated lattices, Nelson residuated lattices and Nelson paraconsistent residuated lattices, we provide a natural common generalization of them.

The geometrical origin of the strain-twist coupling in double helices [PDF]

open access: yesAIP Advances, 2011
A simple geometrical explanation for the counterintuitive phenomenon when twist leads to extension in double helices is presented. The coupling between strain and twist is investigated using a tubular description.

Non-involutive twist-structures [PDF]

open access: yesLogic Journal of the IGPL, 2018
A recent paper by Jakl, Jung and Pultr (2016, Electron. Notes Theor. Comput. Sci., 325, 201–219) succeeded for the first time in establishing a very natural link between bilattice logic and the duality theory of d-frames and bitopological spaces.

Atomic simulations of twist grain boundary structures and deformation behaviors in aluminum

open access: yesAIP Advances, 2017
The structures and behaviors of grain boundaries (GBs) have profound effects on the mechanical properties of polycrystalline materials. In this paper, twist GBs in aluminum were investigated with molecular dynamic simulations to reveal their atomic ...

Reconfiguring nucleation for CVD growth of twisted bilayer MoS2 with a wide range of twist angles

open access: yesNature Communications
Twisted bilayer (TB) transition metal dichalcogenides (TMDCs) beyond TB-graphene are considered an ideal platform for investigating condensed matter physics, due to the moiré superlattices-related peculiar band structures and distinct electronic ...

Structure of nanoscale-pitch helical phases: blue phase and twist-bend nematic phase resolved by resonant soft X-ray scattering [PDF]

open access: yesSoft Matter, 2017
Periodic structures of phases with orientational order of molecules, but homogenous electron density distribution: a short pitch cholesteric, blue phase and twist-bend nematic phase, were probed by a resonant soft x-ray scattering (RSoXS) at the carbon K-

Phonons in twisted transition-metal dichalcogenide bilayers: Ultrasoft phasons and a transition from a superlubric to a pinned phase

open access: yesPhysical Review Research, 2020
The tunability of the interlayer coupling by twisting one layer with respect to another layer of two-dimensional materials provides a unique way to manipulate the phonons and related properties.

Twist defect in chiral photonic structures. [PDF]

open access: yesPhysical Review Letters, 2002
We demonstrate that twisting one part of a chiral photonic structure about its helical axis produces a single circularly polarized localized mode that gives rise to an anomalous crossover in propagation.
