Twist Phase Matching in Two-Dimensional Materials
Physical Review Letters, 2023 Optical phase matching involves establishing a proper phase relationship between the fundamental excitation and generated waves to enable efficient optical parametric processes. It is typically achieved through birefringence or periodic polarization. Here, we report that the interlayer twist angle in two-dimensional (2D) materials creates a nonlinear ...

A generalized density-modulated twist-splay-bend phase of banana-shaped particles [PDF]
Nature Communications, 2021 The so-called twist-bend and splay-bend nematic liquid crystal phases are important concepts for studying bent-core mesogens. Chiappini et al. use a theory/simulation approach to suggest that the transition proceed via a twist-splay-bend phase which may ...

Nanoparticle-induced twist-grain boundary phase
Physical Review E, 2014 By means of high-resolution ac calorimetry and polarizing optical microscopy, it is demonstrated that surface-functionalized spherical CdSSe nanoparticles induce a twist-grain boundary phase when dispersed in a chiral liquid crystal. These nanoparticles can effectively stabilize the one-dimensional lattice of screw dislocations, thus establishing the ...

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.

Аngular optical characteristics of a standard twist indicator with a phase compensator [PDF]
Известия Саратовского университета. Новая серия: Физика, 2022 Background and Objectives: One of the disadvantages of a liquid crystal display device for information on the twist effect is its relatively narrow viewing angle.

F1000Research, 2023 Three parameters are important to characterize a circadian and in general any biological clock: period, phase and amplitude. While circadian periods have been shown to correlate with entrainment phases, and clock amplitude influences the phase response ...

Correlated insulating phases in the twisted bilayer graphene* [PDF]
Chinese Physics B, 2021 We review analytical and numerical studies of correlated insulating states in twisted bilayer graphene, focusing on real-space lattice models constructions and their unbiased quantum many-body solutions. We show that by constructing localized Wannier states for the narrow bands, the projected Coulomb interactions can be approximated by interactions of ...
