Chiral field
Webキラリティー (英語: chirality) は、3次元の図形や物体や現象が、その鏡像と重ね合わすことができない性質である。. キラリティがあることをキラル (chiral) という。英語風の発音でカイラリティ、カイラルともいう 。 これらの語はギリシャ語で「手」を意味する χειρ (cheir) が語源である。

WebFeb 6, 2024 · A chiral reaction field with thermally invertible helical sense enables control of the helicity of the reaction product, which is a central challenge in asymmetric synthesis that has yet to be overcome. WebThe chiral symmetry transformation can be divided into a component that treats the left-handed and the right-handed parts equally, known as vector symmetry, and a component that actually treats them differently, known as axial symmetry. (cf. Current algebra.) A scalar field model encoding chiral symmetry and its breaking is the chiral model.
WebMay 21, 2024 · As shown in fig. S10, C/C 0 of the chiral field is as large as 18 under σ− excitation, where C 0 is the value of optical chirality for a σ− polarized plane wave in a vacuum. C/C 0 has the opposite distribution under σ+ excitation with a maximum value of 8, indicating the intrinsic chirality for this antenna. WebChirality / k aɪ ˈ r æ l ɪ t iː / is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ (kheir), "hand", a familiar chiral object.. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. Conversely, a mirror image of an achiral object, such as …
