WebApr 14, 2024 · Chiral enantiomer recognition has important research significance in the field of analytical chemistry research. At present, most prepared chiral sensors are used for recognizing amino acids, while they are rarely used in the identification of drug intermediates. This work found that combining CS and reduced graphene oxide can … WebThis inevitably hinders their potential applications in the fields requiring sharp resonance with strong field enhancement. For example, chiral lasing and quantum entanglement. [31, 32] To address this challenge, the idea of combining high-Q quasi-BICs resonances with chirality seems promising. To this end, several pioneering studies reported ...

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. WebDec 27, 2012 · Recently, Tang and Cohen [Y. Tang and A. E. Cohen, Science 332, 333 (2011)] proposed and demonstrated the use of ``superchiral'' electromagnetic fields to enhance optical enantioselectivity. Their work generated much excitement as enantioselective signals are typically quite small, and it appeared that the enhancement … Webwhere is a dimensionless coupling. In differential-geometric language, the field is a section of a principal bundle: with fibres isomorphic to the principal homogeneous space for M (hence why this defines the principal chiral model. The "chiral" is due to the complex structure of the Riemann surface, allowing a notion of holomorphicity, identifiable with … chinook crafts
