“Chiral” and “non-chiral” 3d Seiberg duality [PDF]
Journal of High Energy Physics, 2020 Abstract We propose a Seiberg duality for a 3d $$ \mathcal{N} $$ N = 2 Spin (7) gauge theory with F spinor matters. For F ≥ 6, the theory allows a magnetic dual description with an SU(F −4) gauge group. The matter content

Chiral Photons from Chiral Gravitational Waves [PDF]
Physical Review Letters, 2019 We show that a parity-breaking uniform (averaged over all directions on the sky) circular polarization of amplitude $V_{00} \simeq 2.6 \times 10^{-17}\, Δχ(r/0.06)$ can be induced by chiral gravitational-wave (GW) background with tensor-to-scalar ratio $r$ and chirality parameter $Δχ$ (which is $\pm1$ for a maximally chiral background).

Optical properties of planar chiral meta-materials [PDF]
, 2002 The polarization state of visible light is found to be altered upon reflection from artificial two-dimensional chiral media. Arrays of metallic planar chiral structures were fabricated by electron beam lithography and ion beam milling. The characteristic

Pharmaceuticals, 2023 Chirality is a major theme in the design, discovery, and development of new drugs. Historically, pharmaceuticals have been synthesized as racemic mixtures. However, the enantiomeric forms of drug molecules have distinct biological properties.

Stereoselective Synthesis of Flavonoids: A Brief Overview
Molecules, 2023 Stereoselective synthesis has been emerging as a resourceful tool because it enables the obtaining of compounds with biological interest and high enantiomeric purity. Flavonoids are natural products with several biological activities.

Multicritical matrix models and the chiral phase transition [PDF]
, 1998 Universality of multicritical unitary matrix models is shown and a new scaling behavior is found in the microscopic region of the spectrum, which may be relevant for the low energy spectrum of the Dirac operator at the chiral phase ...

Constraints on chiral operators in N=2 SCFTs [PDF]
, 2014 : We study certain higher-spin chiral operators in (formula presented)(formula presented) superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized Argyres-Seiberg-Gaiotto duality (“type A”

Synthesis of alpha,gamma-Chiral Trifluoromethylated Amines through the Stereospecific Isomerization of alpha-Chiral Allylic Amines [PDF]
, 2022 Chiral gamma-branched aliphatic amines are present in a large number of pharmaceuticals and natural products. However, enanti-oselective methods to access these compounds are scarce, and rely on the use of designed chiral transition-metal complexes ...
