The effect of pretilt and twisted angle on twisted nematic liquid crystal filter
Журнал технической физики, 2018 The effect of pretilt and twisted angle on twisted nematic liquid crystal filter (TNLCF) is studied theoretically and experimentally in this paper, based on the birefringence and distortion characteristic of twisted nematic liquid crystal, the output performance of TNLCF has been analyzed through numerical simulation firstly, then the corresponding ...

Twisted angles for central configurations formed by two twisted regular polygons
Journal of Differential Equations, 2012 In this paper, we study the necessary conditions and sufficient conditions for the twisted angles of the central configurations formed by two twisted regular polygons, specially, we prove that for the 2N-body problems, the twisted angles must be$θ=0 {or} θ=π/N$.

Finite element simulation of twist forming process to study twist springback pattern
MATEC Web of Conferences, 2017 Springback is one of the most common defects found in the metal forming of automotive parts. There are three conditions which can be considered as springback i.e. flange angle change, sidewall curl and twist springback and among them, twist springback is

Disorder in twisted bilayer graphene
Physical Review Research, 2020 We develop a theory for a type of disorder in condensed matter systems arising from local twist-angle fluctuations in two strongly coupled van der Waals monolayers twisted with respect to each other to create a flat-band moiré superlattice.

Tunable Electronic Structure in Twisted Bilayer WTe2
Frontiers in Physics, 2022 The moiré pattern restricts the electronic states of transition metal bilayers, thus extending the concept of the magic angle found in twisted bilayer graphene to semiconductors.
