Chiral orbital lasing in a twisted bilayer metasurface [PDF]
Nature CommunicationsChirality is a fundamental concept in physics, core to many phenomena in nonlinear optics, quantum physics and topological photonics. Photons are intrinsically chiral when carrying spin angular momentum, whereas orbital angular momentum can induce ...

Chirality and Symmetry Measures: A Transdisciplinary Review
Entropy, 2003 Many quantitative measures of the degree of chirality or symmetry of a set have been proposed in the literature. The main approaches from various areas are reviewed: chemistry, physics, mathematics, computer sciences, biology, and psychophysics ...

Enhancement of Optical Chirality Using Metasurfaces for Enantiomer-Selective Molecular Sensing
Applied Sciences, 2021 Circular dichroism (CD) is a physical property observed in chiral molecules by inducing the difference of absorption between left- and right-handed circularly polarized light (CPL). Circular dichroism spectroscopy is widely used in the field of chemistry

On the role of chirality flips for the muon magnetic moment and its relation to the muon mass
Frontiers in Physics, 2022 The muon mass and the anomalous magnetic moment aμ are quantities which require chirality flips, i.e., transitions between left- and right-handed muons. Muon chirality flips are connected to electroweak symmetry breaking and Yukawa couplings.

Chiral limit of nuclear physics [PDF]
Physical Review C, 1997 We study nuclear physics in the chiral limit ($m_u$, $m_d=0$) in which the pion mass vanishes. We find that the deuteron mass is changed little, but that P--wave nucleon--nucleon scattering volumes are infinite. This motivates an investigation of the possibilities that there could be a two--nucleon $^3P_0$ bound state, and that the nuclear matter ...

INSTANTONS AND CHIRAL ANOMALY IN FUZZY PHYSICS [PDF]
International Journal of Modern Physics A, 2001 In continuum physics, there are important topological aspects like instantons, θ-terms and the axial anomaly. Conventional lattice discretizations often have difficulties in treating one or the other of these aspects. In this paper, we develop discrete quantum field theories on fuzzy manifolds using noncommutative geometry.

Thermal Effects on Optical Chirality, Mechanics, and Associated Symmetry Properties
Optics, 2023 A review is provided here about the thermal effects on optical chirality. To this goal, chiral objects dispersed in an embedding fluid are examined for their magnetoelectric coupling.

Chirality through classical physics [PDF]
European Journal of Physics, 2020 Abstract Chirality, or handedness, is a topic that is common in biology and chemistry, yet is rarely discussed in physics courses. We provide a way of introducing the topic in classical physics, and demonstrate the merits of its inclusion—such as a simple way to visually introduce the concept of symmetries in physical law—along with ...
